[ceph-client] Validate failure domain support for replica count per pool

Browse Source 
Ensure each pool is configured with enough failure domains to
satisfy the pool's replica size requirements. If any pool does
not have enough failure domains to satisfy the pool's replica size,
then fail the ceph deployment.
