tox: Misc fixes

- Use 'ignore_basepython_conflict' so we can simply define 'basepython'
  on the base testenv
- Add an '.stestr.conf' file, allowing us to stop specifying the
  '--test-path' argument manually
- Call 'sphinx-build' directly instead of using the 'build_sphinx'
  distutils extension, which pbr is deprecating. This requires a fix to
  the docs but allows us to remove some noise from 'setup.cfg'
- Fix some indentation and remove some unnecessary configuration
