This repo is now testing only with Python 3, so let's 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 - Update classifiers - Use newer openstackdocstheme, Sphinx, os-api-ref versions, remove unused mock requirement Change-Id: If7db350ea55a5edf7055ce049d27d9412b0e40bc
