Make a few cleanups:
- Remove python 2.7 stanza from setup.py
- Add requires on python >= 3.6 to setup.cfg so that pypi and pip
know about the requirement
- Remove obsolete sections from setup.cfg:
* Wheel is not needed for python 3 only repo
* Some other sections are obsolete
- Use sphinx-build everywhere
- Update classifiers
- Update requirements, no need for python_version anymore

This is a manual sync with global-requirements in order to verify that
python-monascaclient is compatible and ready.
I needed to remove argpase, as it isn't in g-r and also isn't needed.
