Flip flopped all of the git repos

On all of our projects were were depending on git.openstack.org to be
always available and the definitive source for all of our git repos.
Sadly git.openstack.org has frequent timeouts and has proven itself to
be unpredictable. To aid in deployments and ensure better overall
deployment performance all of the project git repos have been flip
flipped. Now github.com/openstack will be used for all clone operations
as the primary git repository and if there are issues with github we will
fall back to git.openstack.org.
