* manifests/site.pp: Use distinct manifests for git.o.o and git.o.o
backends. This allows for the haproxy server to not serve git content
and purely be a load balancer.
* modules/cgit/manifests/init.pp: Remove haproxy from cgit module.
Remove stale xinetd cleanup. Select git daemon port when selecting
HTTP(S) ports.
* modules/openstack_project/manifests/git.pp: Make git.pp a manifest to
load balance git servers with haproxy.
* modules/openstack_project/manifests/git_backend.pp: New manifest to
manage servers that actually serve git content. They sit behind a load
balancer.
* modules/openstack_project/manifests/review.pp: Stop replicating repos
to git load balancer.
