Description of your changes:
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.

Which issue is resolved by this Pull Request:
Resolves #5091
