Add ceph-calamari role for deploying Calamari

The reason I've got that check is that calamari-ctl actually starts those services after it does some config, i.e. I probably don't want chef to start them before calamari-ctl is run, but you're right it would be better if chef just kept an eye on them with a chef service resource.
