Check total pg count for the cluster vs osd count and max pgs per osd
before allowing pool creation, pg_num change, or pool size change.
"in" OSDs are the ones we distribute data too, so this should be the right
count to use. (Whether they happen to be up or down at the moment is
incidental.)
If the user really wants to create the pool, they can change the
configurable limit.

BlueStore enables CRC by default, so this is a dup and gains
no more benefits.
Turn this off by default, which is good for performance.

This introduces two config parameters:
mds_cache_memory_limit: Sets the soft maximum of the cache to the given
byte count. (Like mds_cache_size, this doesn't actually limit the maximum
size of the cache. It just dictates the steady-state size.)
mds_cache_reservation: This replaces mds_health_cache_threshold everywhere
except the Beacon heartbeat sent to the mons. The idea here is to specify a
reservation of memory (5% by default) for operations and the MDS tries to
always maintain that reservation. So, the MDS will recall caps from clients
when it begins dipping into its reservation of memory.
mds_cache_size still limits the cache by Inode count but is now by-default 0
(i.e. unlimited). The new preferred way of specifying cache limits is by memory
size. The default is 1GB.
