tripleo cephadm deploy has require_min_compat_client luminous

[John Fulton]

After using cephadm to deploy ceph with tripleo using the main branch the default client version is lumionus.

[ceph: root@oc0-controller-0 /]# ceph osd dump | grep require_min_compat_client
require_min_compat_client luminous
[ceph: root@oc0-controller-0 /]#

However, we specifically had the following patch to set this to mimic:

 https://review.opendev.org/c/openstack/tripleo-heat-templates/+/773539

in order to have: "simplified image clone semantics where non-protected snapshots can be cloned; and snapshots with linked clones can be removed and the space automatically reclaimed once all remaining linked clones are detached. This feature is enabled by default if the OSD “require-min-compat-client” flag is set to mimic or later; or can be overridden via the “rbd_default_clone_format” configuration option."

I believe this is a regression because we removed the ceph-ansible THT to set this but didn't add it to the cephadm THT. This bug should be used to track adding a similar task back for the cephadm case.

    Enforce minimum Ceph client version to Mimic

    This is so that we can take advantage of the deferred deletion
    feature in Cinder. This change is done in Ansible instead of
    TripleO Heat Templates so that it is deployed_ceph compatible
    while still having an effect when deployed_ceph is not used.
