After upgrade from RHCS 3 to RHCS 4 the Ceph Features command is still reporting Luminous

Issue

After an upgrade from Red Hat Ceph Storage 3 to Red Hat Ceph Storage 4 the ceph features command output still reports components are running Luminous (RHCS 3) features even though the version of the components are running Nautilus (RHCS 4)
