Cleanup py27 support

This repo is now testing only with Python 3, so let's make
a few cleanups:
- Remove python 2.7 stanza from setup.py
- Remove obsolete sections from setup.cfg
- Update classifiers
- Switch from python2 only oslosphinx to openstackdocsthemem
- Remove install_command from tox.ini, the default is fine
- Switch to hacking 3.0 to support python 3
