The ceph master repository is slow and the centos build often fails due
to timeouts fetching the ceph repo GPG key.
Switching to a more reliable mirror should improve things.

The default timeout for Ceph GPG rpm key retrieval is 30 seconds.
In my testing, the GPG key takes approximately 50 seconds to download
often resulting in a failure to build containers that need to retrieve
the Ceph GPG sign key. Crank up the timer to 90 seconds so the key
is more likely to be downloaded, allowing images to be built.

Ceph packages need to be installed in nova, glance, and cinder.
Once that is done, Ceph works like a champ!
