Validate requested Ceph Placement Groups.
In Ceph Lumionus and newer the Placement Group overdose protection check (https://ceph.com/community/new-luminous-pg-overdose-protection) is executed by Ceph before a pool is created. If the check does not pass, then the pool is not created. When TripleO deploys Ceph it triggers ceph-ansible which creates the pools that OpenStack needs. This validation runs the same check that the overdose protection uses to determine if the user should update their CephPools, PG count, or number of OSD. Without this check a deployer may have to wait until after Ceph is running but before the pools are created to realize the deployment will fail.
