Hitachi drivers do not allow cloning volume to a different size

[Sean McGinnis]

It's possible to create a volume from a source volume with a different size. The create_cloned_volume call into the driver could have a larger volume['size'] than the source volume. So the driver will need to create the clone, then check if it needs to extend the volume to a new size.

    Hitachi drivers: resize volume if cloned image is larger

    Extend volume if during create_volume_from_snapshot() the new volume
    is larger than the image it was cloned from. Extended test cases to
    cover the change.
