Cleanup py27 support
This repo is now testing only with Python 3, so let's make
a few cleanups:
- Remove obsolete section from setup.cfg
- Use newer openstackdocstheme and Sphinx version for python 3
- Remove install_command from tox.ini, the default is fine
- Move basepython into testenv
- Update bashate version
