Description of problem: Improve Ceph integration with RHELOSP. In particular this means ensuring that we have working support for using Ceph: - As the backing for the instance store for live migration - As the backing for glance images - As the backing for cinder volumes ...and verifying the correct configurations that the automated deployment tools should be using.
