Upgrade ceph release to Luminous

The Pike UCA repo has been bumped to include the recently released
Ceph LTS, Luminous (12.x). Since the UCA repo is installed almost
globally in our deployment, this creates package conflicts when we
attempt to deploy the former Ceph LTS, Jewel (10.x) releases.

We will bump our Ceph stable release to the Luminous release for Pike
and later to avoid the package conflicts with UCA.

This also adds the ceph-mgr role execution since the ceph-mgr service
is required in Luminous. See http://docs.ceph.com/docs/master/mgr/ for
more information.
