The PG count on metadata pools should default to rgw_rados_pool_pg_num_min instead of the more general default pg count. This means rgw pools will default to 8 PGs instead of 32 PGs, which means a lot more pools can be created before hitting the default PG limit. Signed-off-by: Travis Nielsen <tnielsen@redhat.com>
