### Summary
Fixes issue #16.


### Details and comments
This PR addresses issue #16 by adding an `options` field in `IBMExperimentService`, intended to be changed via `IBMExperimentService.set_option()`, with the `prompt_for_delete` option disabling the confirmation prompt used when deleting experiment/analysis result/figure. This PR also slightly refactored the code displaying those prompts so they all use the same `_confirm_delete()` method.

+Contributing
+============
+
+First read the overall project contributing guidelines. These are all
+included in the qiskit documentation:
+
+https://qiskit.org/documentation/contributing_to_qiskit.html
+
+
+Contributing to Qiskit IBM Runtime
+---------------------------
+
+In addition to the general guidelines there are specific details for
+contributing to the Qiskit IBM Runtime, these are documented below.
+
+### Pull request checklist
+
+When submitting a pull request and you feel it is ready for review,
+please ensure that:
+
+1. The code follows the code style of the project and successfully
+   passes the tests. For convenience, you can execute `tox` locally,
+   which will run these checks and report any issues.
+2. The documentation has been updated accordingly. In particular, if a
+   function or class has been modified during the PR, please update the
+   *docstring* accordingly.
+3. If it makes sense for your change that you have added new tests that
+   cover the changes.
+4. Ensure that if your change has an end user facing impact (new feature,
+   deprecation, removal etc) that you have added a reno release note for that
+   change and that the PR is tagged for the changelog.
+
+### Changelog generation
+
+The changelog is automatically generated as part of the release process
+automation. This works through a combination of the git log and the pull
+request. When a release is tagged and pushed to github the release automation
+bot looks at all commit messages from the git log for the release. It takes the
+PR numbers from the git log (assuming a squash merge) and checks if that PR had
+a `Changelog:` label on it. If there is a label it will add the git commit
+message summary line from the git log for the release to the changelog.
+
+If there are multiple `Changelog:` tags on a PR the git commit message summary
+line from the git log will be used for each changelog category tagged.
+
+The current categories for each label are as follows:
+
+| PR Label               | Changelog Category |
+| -----------------------|--------------------|
+| Changelog: Deprecation | Deprecated         |
+| Changelog: New Feature | Added              |
+| Changelog: API Change  | Changed            |
+| Changelog: Removal     | Removed            |
+| Changelog: Bugfix      | Fixed              |
+
+### Release Notes
+
+When making any end user facing changes in a contribution we have to make sure
+we document that when we release a new version of qiskit-ibm. The
+expectation is that if your code contribution has user facing changes that you
+will write the release documentation for these changes. This documentation must
+explain what was changed, why it was changed, and how users can either use or
+adapt to the change. The idea behind release documentation is that when a naive
+user with limited internal knowledege of the project is upgrading from the
+previous release to the new one, they should be able to read the release notes,
+understand if they need to update their program which uses qiskit, and how they
+would go about doing that. It ideally should explain why they need to make
+this change too, to provide the necessary context.
+
+To make sure we don't forget a release note or if the details of user facing
+changes over a release cycle we require that all user facing changes include
+documentation at the same time as the code. To accomplish this we use the
+[reno](https://docs.openstack.org/reno/latest/) tool which enables a git based
+workflow for writing and compiling release notes.
+
+#### Adding a new release note
+
+Making a new release note is quite straightforward. Ensure that you have reno
+installed with::
+
+    pip install -U reno
+
+Once you have reno installed you can make a new release note by running in
+your local repository checkout's root::
+
+    reno new short-description-string
+
+where short-description-string is a brief string (with no spaces) that describes
+what's in the release note. This will become the prefix for the release note
+file. Once that is run it will create a new yaml file in releasenotes/notes.
+Then open that yaml file in a text editor and write the release note. The basic
+structure of a release note is restructured text in yaml lists under category
+keys. You add individual items under each category and they will be grouped
+automatically by release when the release notes are compiled. A single file
+can have as many entries in it as needed, but to avoid potential conflicts
+you'll want to create a new file for each pull request that has user facing
+changes. When you open the newly created file it will be a full template of
+the different categories with a description of a category as a single entry
+in each category. You'll want to delete all the sections you aren't using and
+update the contents for those you are. For example, the end result should
+look something like::
+
+```yaml
+features:
+  - |
+    Introduced a new feature foo, that adds support for doing something to
+    ``QuantumCircuit`` objects. It can be used by using the foo function,
+    for example::
+
+      from qiskit import foo
+      from qiskit import QuantumCircuit
+      foo(QuantumCircuit())
+
+  - |
+    The ``qiskit.QuantumCircuit`` module has a new method ``foo()``. This is
+    the equivalent of calling the ``qiskit.foo()`` to do something to your
+    QuantumCircuit. This is the equivalent of running ``qiskit.foo()`` on
+    your circuit, but provides the convenience of running it natively on
+    an object. For example::
+
+      from qiskit import QuantumCircuit
+
+      circ = QuantumCircuit()
+      circ.foo()
+
+deprecations:
+  - |
+    The ``qiskit.bar`` module has been deprecated and will be removed in a
+    future release. Its sole function, ``foobar()`` has been superseded by the
+    ``qiskit.foo()`` function which provides similar functionality but with
+    more accurate results and better performance. You should update your calls
+    ``qiskit.bar.foobar()`` calls to ``qiskit.foo()``.
+```
+
+You can also look at other release notes for other examples.
+
+You can use any restructured text feature in them (code sections, tables,
+enumerated lists, bulleted list, etc) to express what is being changed as
+needed. In general you want the release notes to include as much detail as
+needed so that users will understand what has changed, why it changed, and how
+they'll have to update their code.
+
+After you've finished writing your release notes you'll want to add the note
+file to your commit with `git add` and commit them to your PR branch to make
+sure they're included with the code in your PR.
+
+##### Linking to issues
+
+If you need to link to an issue or other github artifact as part of the release
+note this should be done using an inline link with the text being the issue
+number. For example you would write a release note with a link to issue 12345
+as:
+
+```yaml
+fixes:
+  - |
+    Fixes a race condition in the function ``foo()``. Refer to
+    `#12345 <https://github.com/Qiskit/qiskit-ibm-runtime/issues/12345>`_ for
+    more details.
+```
+
+#### Generating the release notes
+
+After release notes have been added if you want to see what the full output of
+the release notes. In general the output from reno that we'll get is a rst
+(ReStructuredText) file that can be compiled by
+[sphinx](https://www.sphinx-doc.org/en/master/). To generate the rst file you
+use the ``reno report`` command. If you want to generate the full Qiskit IBM provider
+release notes for all releases (since we started using reno during 0.9) you just
+run::
+
+    reno report
+
+but you can also use the ``--version`` argument to view a single release (after
+it has been tagged::
+
+    reno report --version 0.9.0
+
+At release time ``reno report`` is used to generate the release notes for the
+release and the output will be submitted as a pull request to the documentation
+repository's [release notes file](
+https://github.com/Qiskit/qiskit/blob/master/docs/release_notes.rst)
+
+#### Building release notes locally
+
+Building The release notes are part of the standard qiskit-ibm
+documentation builds. To check what the rendered html output of the release
+notes will look like for the current state of the repo you can run:
+`tox -edocs` which will build all the documentation into `docs/_build/html`
+and the release notes in particular will be located at
+`docs/_build/html/release_notes.html`
+
+## Installing Qiskit IBM Provider from source
+Please see the [Installing IBM Quantum Provider from
+Source](https://qiskit.org/documentation/contributing_to_qiskit.html#installing-ibm-quantum-provider-from-source)
+section of the Qiskit documentation.
+
+
+### Test
+
+New features often imply changes in the existent tests or new ones are
+needed. Once they're updated/added run this be sure they keep passing.
+
+For executing the tests, a `make test` target is available.
+
+For executing a simple python test manually, you can just run this
+command:
+
+Linux and Mac:
+
+``` {.bash}
+$ python -m unittest test/test_something.py
+```
+
+Windows:
+
+``` {.bash}
+C:\..\> python -m unittest test/test_something.py
+```
+
+The python tests either run locally ("unit tests") or against a remote API ("integration tests") 
+depending on the environment configuration. Check the [workflow definition](.github/workflows/ci.yml), 
+or the examples below for the set of supported environment variables.
+
+Run integration tests against IBM Quantum 
+```bash
+QISKIT_IBM_TOKEN=...                                            # IBM Quantum API token

+QISKIT_IBM_INSTANCE=ibm-q/open/main                             # IBM Quantum provider to use (hub/group/project)
+```
+
+Run integration tests against IBM Cloud
+```bash
+QISKIT_IBM_TOKEN=...                                            # IBM Cloud API key

+QISKIT_IBM_INSTANCE=crn:v1:bluemix:...                          # The CRN value of the Quantum service instance
+```
+
+Run unit tests
+```bash

+To enable integration test cases to run in your private fork, make sure to set above values as 
+[encrypted environment secrets](https://docs.github.com/en/actions/security-guides/encrypted-secrets#creating-encrypted-secrets-for-an-environment). 
+The names of the environments must match the ones that the [CI workflow](.github/workflows/ci.yml) relies

+
+### Style guide
+
+Please submit clean code and please make effort to follow existing
+conventions in order to keep it as readable as possible. We use:
+* [Pylint](https://www.pylint.org) linter
+* [PEP 8](https://www.python.org/dev/peps/pep-0008) style
+* [mypy](http://mypy-lang.org/) type hinting
+
+To ensure your changes respect the style guidelines, you can run the following
+commands:
+
+All platforms:
+
+``` {.sh}
+$> cd out
+out$> make lint
+out$> make style
+out$> make mypy
+```
+
+### Development Cycle
+
+The development cycle for qiskit-ibm  is all handled in the open using
+the project boards in Github for project management. We use milestones
+in Github to track work for specific releases. The features or other changes
+that we want to include in a release will be tagged and discussed in Github.
+As we're preparing a new release we'll document what has changed since the
+previous version in the release notes.
+
+### Branches
+
+* `main`:
+
+The main branch is used for development of the next version of qiskit-ibm.
+It will be updated frequently and should not be considered stable. The API
+can and will change on main as we introduce and refine new features.
+
+* `stable/*` branches:
+Branches under `stable/*` are used to maintain released versions of qiskit-ibm.
+It contains the version of the code corresponding to the latest release for
+that minor version on pypi. For example, stable/0.8 contains the code for the
+0.8.2 release on pypi. The API on these branches are stable and the only changes
+merged to it are bugfixes.
+
+### Release cycle
+
+When it is time to release a new minor version of qiskit-ibm we will:
+
+1.  Create a new tag with the version number and push it to github
+2.  Change the `main` version to the next release version.
+
+The release automation processes will be triggered by the new tag and perform
+the following steps:
+
+1.  Create a stable branch for the new minor version from the release tag
+    on the `main` branch
+2.  Build and upload binary wheels to pypi
+3.  Create a github release page with a generated changelog
+4.  Generate a PR on the meta-repository to bump the Qiskit IBM Provider version and
+    meta-package version.
+
+The `stable/*` branches should only receive changes in the form of bug
+fixes.

+          that You distribute, all copyright, patent, trademark, and
+          attribution notices from the Source form of the Work,
+          excluding those notices that do not pertain to any part of
+          the Derivative Works; and
+
+      (d) If the Work includes a "NOTICE" text file as part of its
+          distribution, then any Derivative Works that You distribute must
+          include a readable copy of the attribution notices contained
+          within such NOTICE file, excluding those notices that do not
+          pertain to any part of the Derivative Works, in at least one
+          of the following places: within a NOTICE text file distributed
+          as part of the Derivative Works; within the Source form or
+          documentation, if provided along with the Derivative Works; or,
+          within a display generated by the Derivative Works, if and
+          wherever such third-party notices normally appear. The contents
+          of the NOTICE file are for informational purposes only and
+          do not modify the License. You may add Your own attribution
+          notices within Derivative Works that You distribute, alongside
+          or as an addendum to the NOTICE text from the Work, provided
+          that such additional attribution notices cannot be construed
+          as modifying the License.
+
+      You may add Your own copyright statement to Your modifications and

+      reproduction, and distribution of the Work otherwise complies with
+      the conditions stated in this License.
+
+   5. Submission of Contributions. Unless You explicitly state otherwise,
+      any Contribution intentionally submitted for inclusion in the Work
+      by You to the Licensor shall be under the terms and conditions of
+      this License, without any additional terms or conditions.
+      Notwithstanding the above, nothing herein shall supersede or modify
+      the terms of any separate license agreement you may have executed
+      with Licensor regarding such Contributions.
+
+   6. Trademarks. This License does not grant permission to use the trade
+      names, trademarks, service marks, or product names of the Licensor,
+      except as required for reasonable and customary use in describing the
+      origin of the Work and reproducing the content of the NOTICE file.

+      agreed to in writing, Licensor provides the Work (and each
+      Contributor provides its Contributions) on an "AS IS" BASIS,
+      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
+      implied, including, without limitation, any warranties or conditions

+      PARTICULAR PURPOSE. You are solely responsible for determining the
+      appropriateness of using or redistributing the Work and assume any
+      risks associated with Your exercise of permissions under this License.
+
+   8. Limitation of Liability. In no event and under no legal theory,
+      whether in tort (including negligence), contract, or otherwise,
+      unless required by applicable law (such as deliberate and grossly
+      negligent acts) or agreed to in writing, shall any Contributor be
+      liable to You for damages, including any direct, indirect, special,
+      incidental, or consequential damages of any character arising as a
+      result of this License or out of the use or inability to use the
+      Work (including but not limited to damages for loss of goodwill,
+      work stoppage, computer failure or malfunction, or any and all
+      other commercial damages or losses), even if such Contributor
+      has been advised of the possibility of such damages.
+
+   9. Accepting Warranty or Additional Liability. While redistributing
+      the Work or Derivative Works thereof, You may choose to offer,
+      and charge a fee for, acceptance of support, warranty, indemnity,
+      or other liability obligations and/or rights consistent with this
+      License. However, in accepting such obligations, You may act only
+      on Your own behalf and on Your sole responsibility, not on behalf
+      of any other Contributor, and only if You agree to indemnify,
+      defend, and hold each Contributor harmless for any liability
+      incurred by, or claims asserted against, such Contributor by reason
+      of your accepting any such warranty or additional liability.
+

+Qiskit Experiment Service (:mod:`qiskit_ibm_experiment`)
+==========================================
+
+.. currentmodule:: qiskit_ibm_experiment
+
+Logging
+-------
+
+Qiskit IBM Experiment Service uses the ``qiskit_ibm_experiment`` logger.
+
+Two environment variables can be used to control the logging:
+
+    * ``QISKIT_IBM_EXPERIMENT_LOG_LEVEL``: Specifies the log level to use.
+      If an invalid level is set, the log level defaults to ``WARNING``.
+      The valid log levels are ``DEBUG``, ``INFO``, ``WARNING``, ``ERROR``, and ``CRITICAL``
+      (case-insensitive). If the environment variable is not set, then the parent logger's level
+      is used, which also defaults to ``WARNING``.
+    * ``QISKIT_IBM_EXPERIMENT_LOG_FILE``: Specifies the name of the log file to use. If specified,
+      messages will be logged to the file only. Otherwise messages will be logged to the standard
+      error (usually the screen).
+
+For more advanced use, you can modify the logger itself. For example, to manually set the level
+to ``WARNING``::
+
+    import logging
+    logging.getLogger('qiskit_ibm_experiment').setLevel(logging.WARNING)
