1. Renamed current test_user.py to test_user_new.py
2. Created new test_user.py for new User test case stubs in the new docstring format
3. Once the test stubs are created, the tests in test_user_new.py will be moved to test_user.py. Then test_user_new.py will be deleted
Positive create test cases completed
Fixed failing Org tests
Completed Create, Delete and Update Scenarios
Adding support for GPG keys via hammer cli.

Added support for GPG keys via Hammer CLI, including a factory method.
The following pieces of imformation are important to take into
consideration when writing the tests:

* Most, if not all, subcommands that are derived from Katello will
  require ``organization-id`` as an argument for some of its actions.
  For instance, ``hammer gpg list`` will *not* give you a list of all
  available gpg keys in the system, but only those keys for the provided
  ``organization-id``.
* Searching for Katello subcommands follows *ElasticSearch* syntax. So,
  instead of:

```bash
$ hammer gpg list --search name='foo'
```

You have to use:

```bash
$ hammer gpg list --search name:'foo'
```

* The following issues have been found and filed:
  * http://projects.theforeman.org/issues/4272
  * http://projects.theforeman.org/issues/4271
  * http://projects.theforeman.org/issues/4263
  * http://projects.theforeman.org/issues/4262
Separated My Account tests and created a new test_myaccount.py
Added decorator for all CLI gpg key tests.

The gpg cli subcommand is currently affected by several issues, so they
will be skipped for the time being:

```bash
nosetests -c robottelo.properties tests/cli/test_gpgkey.py
