Organization deletion by ID, Name and Label.

Updated test that deleted organization by ID to use the organization ID
instead of its name, now that you can be specific about deleting by
either ID, Name, or Label via the CLI. Also removed Bugzilla decorator
and added individual tests for each test.

```bash
$ nosetests -c robottelo.properties tests/foreman/cli/test_org.py:TestOrg.test_bugzilla_1076568_1 tests/foreman/cli/test_org.py:TestOrg.test_bugzilla_1076568_2 tests/foreman/cli/test_org.py:TestOrg.test_bugzilla_1076568_3

Organization deletion by ID, Name and Label.
Expose the TimeOut argument for CLI commands.

There are some CLI actions, such as content view promotions, can take a
bit longer to return and the default timeout of 50 seconds, which was
not exposed, was not long enough for some of our tests.

I have exposed the (optional) timeout argument via CLI's base class.
Also, I have set a default timeout of 120 seconds for content view
publishing for this PR.
