mon: move `osd_pool_default_pg_num` in `ceph-defaults`

`osd_pool_default_pg_num` parameter is set in `ceph-mon`.
When using ceph-ansible with `--limit` on a specifc group of nodes, it
will fail when trying to access this variables since it wouldn't be
defined.

Closes: https://bugzilla.redhat.com/show_bug.cgi?id=1518696
