    Cluster driver: Blacklist iSCSI/FC volume drivers

    There are critical known issues related to the cluster driver and
    passthrough disks.

    When an instance is failed over, the instance attached volumes need
    to be accessible on the destination host. This will not happen
    transparently for such disks, for which reason the instance may
    bounce between a few nodes and then end up in error state,
    basically defeating the purpose of the cluster driver.

    This change ensures that the Hyper-V Cluster driver rejects
    iSCSI/FC Cinder volumes, raising an error that describes possible
    alternatives.
