The built-in pools device_health_metrics and .nfs created by ceph need to be configured for replicas, failure domain, etc. To support this, we allow the pool to be created as a CR. Since K8s does not support underscores in the resource names the operator must translate this special pool name into the name expected by ceph. This also sets the basis for allowing filesystem data pools to specify the desired pool name instead of requiring a generated name. Signed-off-by: Travis Nielsen <tnielsen@redhat.com>
