    HA: Fix the cluster common tag behaviour with podman

    Since [1,2], HA container image name used in pacemaker are
    look like container-common-tag/<servicename>:pcmklatest.

    Unlike docker, podman prepends a host information in
    front of this tag, which confuses the podman resource
    agent in pacemaker.

    Make the first part of the tag look like a fqdn so that
    podman doesn't change it.
