Subject: [PATCH] ci: deploy rook with mon_warn_on_pool_no_redundancy in
 ceph.conf

In test environments the default pool size is set to 1, so there is no
redundancy. This causes recent Ceph versions to complain with
HEALTH_WARN as POOL_NO_REDUNDANCY get set.

By disabling the mon_warn_on_pool_no_redundancy option in ceph.conf, the
warning is not reported and the cluster is marked HEALTHY.
