* 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.
