    Revert Ceph bridge names to previous values

    When the NIC configs were unified under a single role.role.j2.yaml,
    the bridge name for Ceph roles was changed from "br-storage" or
    "br-bond" to "br-ex". This breaks upgrades which used the original
    NIC config templates. This change reverts those valuse when
    rendering the NIC config templates for CephStorage roles.
