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
- Update requirements, no need for python_version anymore

This is an important update and should be merged ASAP. Latest
release of setuptools 8.0 introduced new rules which make
current constraints on SQLAlchemy invalid.
As a temporary workaround all the jenkins slave nodes have
a cap on setuptools version, but it is going to be removed
soon.
