[Openstack-operators] [Fuel][ceph] Fuel 7.0 Ceph dm-crypt and multi-site redundancy

There are no provisions in fuel currently for more complex operations like
dm-crypt and tuning crush topology. Both can be accomplished post
deployment manually however. For dm-crypt you can remove the osd and Re add
it using ceph-deploy (you will want to update the partition GUID to match
this usage for automatic mounting )

For topology changes, I'd just refer to the crush map documentation.
