CRUSH rule changes not applied once pools exist

[oneswig]

CRUSH rule assignments are not being applied after a pool has been created.

The bug is that updating Ceph pools doesn't evaluate changes in CRUSH rule here: https://github.com/stackhpc/ansible-collection-cephadm/blob/master/plugins/modules/cephadm_pool.py#L304-L305

Adding crush_rule to that list doesn't solve things because it compares pool ID with name, eg 1 with replicated_hdd, so now it always applies the change.

One way to add support for CRUSH rule configuration would be to replace pool IDs with pool names before the comparison is made.
