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
- Update classifiers
