Sphinx and OpenStack documentation standards require the use of
RST formatted documentation.  In order to get out docs integrated
into docs.openstack.org, the following steps must be taken:

1. we need to first convert the documentation to RST
2. sphinx support must be added to the repository
3. project-config must be updated with a publish-docs job

The ability to pubish to docs.openstack.org is a privilege only
available to Big Tent projects.  As a result, we should be taking
advantage of this to help spread the word on our implementation.

Note the documentation was converted with a tool called pandoc
the syntax of which was:
pandoc -f markdown -t rst file.md > z
mv z file.rst

In order for git to preserve history the files have to be git mv'ed
in one commit followed by the pandoc operation in a separate commit.
