* remove azure extras and extras_require support
* Since Azure will be collectionized, the requirements will float more frequently than Ansible releases; the Azure collection needs to host the requirements now.
* Removed the dynamic extras support as well, since Azure was the only thing using it. If we need it again, it's easy to pull back from history.
* Mark azure-requirements as orhpaned.
This keeps the docs around so that existing links from old test runs remain valid.

* Add openssh-client to default docker container.
* Include Azure requirements in default container.
To do so, handling of pip requirements was updated to install each
set of requirements separately and then run a verification pass to
make sure there are no conflicts between requirements.
* Add missing --docker-no-pull option.
* Add documentation for the azure-requirements test.
