Small cleanups

tox.ini:
* Remove install_command, the default is fine
* Move python3 to default environment
* Remove duplicated requirements

setup.cf:
* Remove obsolete section, we never built wheels

doc/requirements.txt:
* update to newer openstackdocstheme

doc/source/conf.py
* Remove obsolete setting of html_last_updated_fmt, this is handled by
  the theme
