Make a few cleanups:
- Remove obsolete sections from setup.cfg
- Switch to using sphinx-build; fix warnings found:
convert unreferenced footnote into normal link
- Cleanup doc/source/conf.py to remove now obsolete content.
- Use newer openstackdocstheme version, update some other versions as
needed
- Remove install_command from tox.ini, the default is fine; cleanup
for python3 only

We want to default to running all tox environments under python 3, so
set the basepython value in each environment.
We do not want to specify a minor version number, because we do not
want to have to update the file every time we upgrade python.
We do not want to set the override once in testenv, because that
breaks the more specific versions used in default environments like
py35 and py36.
