[ceph-pools] Stop setting pgp_num to nautilus based deployments

Browse Source 
Starting in Nautilus, setting pgp_num step is no longer necessary
as long as pgp_num and pg_num currently match, pgp_num will automatically
track any pg_num changes.
More importantly, the adjustment of pgp_num to migrate data and (eventually)
converge to pg_num is done gradually to limit the data migration load on the system.
