Ceph-fs needs pool configuration support

[Chris Sanders]

The Ceph-fs charm has very little configuration options. Especially with the Luminous release moving to BlueStore Ceph-fs needs the ability to configure the pool parameters like erasure vs replicated, weight, compression, failure domain, K M & L value, and erasure algorithm to name a few. Some of these settings can be defaulted to reasonable values, but use cases vary enough that just providing a 3 replica replicated pool is no sufficient in Luminous+
