    New HP LeftHand array iSCSI driver

    This driver is intended to replace the current OpenStack Block
    Storage HP LeftHand (LH) StoreVirtual iSCSI Driver,
    (cinder.volume.drivers.san.HpSanISCSIDriver), by moving the
    existing SSH interface into the new driver to maintain backwards
    compatibility, and add the new LH REST interface for new driver
    features.

    We have the driver broken into 3 files:
    hp_lefthand_iscis.py (common interface)
    hp_lefthand_cliq_proxy.py (old SSH interface)
    hp_lefthand_rest_proxy.py (new REST interface)

    The reason we are doing this is because the SSH interface on LH
    array has connections and performance limitations. These problems
    will be resolved by moving to the new LH OS REST interface. Also,
    new LeftHand array capabilities will only be supported in the
    REST(hplefthandclient) interface.

    To support new driver capabilities (create cloned volume), the
    python REST client (hplefthandclient) is required and can be
    downloaded from the pypi repository:
      http://pypi.python.org/pypi/hplefthandclient.
    This REST client requires LeftHand firmware version 11.5 or
    greater.

    The SSH interface will be phased out over time.
