Clean up tox.ini and document zuul.yaml settings
I tried to remove --sitepacakges and the gate failed
so I added comment and in the .zuul.yaml so future people
will understand why.
I Updated the tox.ini environment description so if someone
does a tox -av it will list all command supportted and a
small description of what
While dcoumenting the zuul.yaml I noticed that I made
patrole-reader a job and I feel that we should also
have it as a gate.
I also saw that extension and multi-node non-voting jobs
where missing reader versions so I added them.
