Andreas Jaeger 7f2b19452f Cleanup py27 support and docs
Make a few cleanups:
- Remove obsolete sections from setup.cfg
- Remove install_command from tox.ini, the default
  is fine
- Switch to sphinx-build
- Enable warnings for doc build, fix all warnings
- Remove git handling from conf.py, openstackdocstheme does this now
- Cleanup tox.ini
