Remove unused iniparse requirement
Update smoke test for available URLs

Rewrite `TestAvailableURLs.test_get_links` to match the response currently
generated by the API.

[BZ 1105773](https://bugzilla.redhat.com/show_bug.cgi?id=1105773) was marked as
VERIFIED on the 10th. As a result, the `skip_if_bug_open` decorator now allows
the test to run. The test expects a flat list of URLs from the API:

    u'/katello/api/content_views/:content_view_id/content_view_puppet_modules',
    u'/katello/api/content_views/:content_view_id/filters',
    u'/katello/api/content_view_versions',
    u'/katello/api/environments',
    u'/katello/api/errata',
    u'/katello/api/gpg_keys',
    u'/katello/api/host_collections',
    u'/katello/api/organizations',
    u'/katello/api/organizations/:organization_id/content_views',
    …

The test was created quite some time back, and in the meantime the API has been
changed. The API actually returns data in this format:

    {u'content_views': {
        u'…': 'u/katello/api/content_views/:id',
        u'…': 'u/katello/api/content_views/:id',
        u'…': 'u/katello/api/content_views/:id',
        u'…': 'u/katello/api/content_views/:id/available_puppet_module_names',
        u'…': 'u/katello/api/content_views/:id/available_puppet_modules',
        u'…': 'u/katello/api/content_views/:id/copy',
        u'…': 'u/katello/api/content_views/:id/environments/:environment_id',
        u'…': 'u/katello/api/content_views/:id/history',
        u'…': 'u/katello/api/content_views/:id/publish',
        u'…': 'u/katello/api/content_views/:id/remove',
        u'…': 'u/katello/api/organizations/:organization_id/content_views',
        u'…': 'u/katello/api/organizations/:organization_id/content_views',
    }, …}

The keys in the outer dict are names like "content_views" or "architectures".
The keys in the inner dict are prose descriptions of corresponding paths.

Fix #1555.
Merge pull request #1560 from Ichimonji10/issue-1555

Update smoke test for available URLs
Added content-view tests related to redhat content.

Added support to handle even redhat content from manifests, to the
`setup_to_create_cv` function.

Note:- No lifecycle env creation required while publishing.

Fixes for formatting and using the proper api sync function call
Few timeout fixes related to UI

Increase the timeout value to avoid timing issues.

Used `wait_until_element` as the element takes time to appear.
Multiple updates to api tests
1. Removed references to decorators.($func) by importing them directly
2. Imported ddt.data as ddt_data to differentiate it from decorators.data - This change will make the api tests consistent with ui/api tests
3. Added pylint disables to make pylint happy for all the files in this commit

Multiple updates to api tests
Merge pull request #1556 from kbidarkar/add-cv-rh_content-tests

Added content-view tests related to redhat content.
Added CLI tests for Docker images.

Added two new CLI tests for creating repositories that use Docker
content. Please see #1550 and #1551 for more information about naming
conventions for Docker repositories. Please note that the existing
synchronization tests are affected by [Bugzilla #1152237](https://bugzilla.redhat.com/show_bug.cgi?id=1152237).

Also removed several Bugzilla decorators as the referred issues had
already been verified and tests were being run.

Finally, updated ``test_positive_update_1`` test as it was trying to
update ``FAKE_1_YUM_REPO`` to ``FAKE_1_YUM_REPO`` and assert that the
URL had been updated :)

All tests pass against nightly build (with some skips due to Bugzilla.)

Drop the * operator from a function call

The `*` operator is a useful tool, but it's also fairly mysterious. Use
`chain.from_iterable` instead.
Added an info blurb linking to new docs

The location of the addition is to keep greater emphasis on the
most important goal of this document.
Links in this document now work properly with sphinx.

Make the readme a real file, not a symlink

The readme should render correctly when processed by rst2html, displayed on
GitHub, or read as a standalone file. In contrast, the main body of
documentation must be compiled before being read. Split the readme and main body
of documentation apart.

Add a table of contents to `docs/index.rst`.

Fix a random error in `robottelo/orm.py`.
