This repo is now testing only with Python 3, so let's make
a few cleanups:
- Remove python 2.7 stanza from setup.py
- Remove obsolete sections from setup.cfg
- Cleanup doc/source/conf.py to remove now obsolete content.
Change-Id: I75cbbde0c0f5fa391d76eac3fea06036b3b836f1
In order to integrate this role with OpenStack-Ansible there needs
to be using standard CONTRIBUTING.rst and README.rst and the same
.gitignore and .gitreview and setup.* pattern as other roles.
Finally an other-requirements.txt, test-requirements.txt and a
tox.ini are introduced as the basis for docs building and testing in
openstack infra.
