Currently the Ceph helm tests pass when the deployed Ceph cluster
is unhealthy. This change expands the cluster status testing
logic to pass when all PGs are active and fail if any PG is
inactive.
The PG autoscaler is currently causing the deployment to deploy
unhealthy Ceph clusters. This change also disables it. It should
be re-enabled once those issues are resolved.
