Description of problem:
Users can create pools with lots of pgs and overload the cluster. Prevent that via a config option that limits the pgs per osd.
See upstream PR https://github.com/ceph/ceph/pull/17427. This will need to be backported to luminous and (maybe) 2.y.
https://github.com/ceph/ceph/pull/17814 is backport PR
