    ScaleIO driver: update_migrated_volume

    This patch implements the update_migrated_volume function.
    Without this change, when the migrate finishes, the original
    volume will be deleted but the name on the new volume will not
    be changed to the old id even though the Cinder database will
    be updated. The volume name is a base64() encoding of the Cinder
    volume id so any calls after the migrate fail since the lookup
    fails.

    Also changed 'SCALEIO' to connector.SCALEIO now that os-brick 0.4.0
    is released.
