CI Watch project started outside of OpenStack infrastructure.
This patch adds missing bits to enables infra testing, documentation
builds, and to make packaging easier if we'd like to do so.
Additional changes to accommodate the template:
* ciwatch/__init__.py renamed to ciwatch/server.pp, and all related
imports updated.
* README.md converted into rst and split up into sections.
