Bug Description

Modify GPFS driver organization so that the code for dealing with moving image files from gpfs-backed glance repository to gpfs-backed volumes resides in clone_image function. This simplifies the code and better follows the intent of the clone_image function.

    GPFS use clone_image for creating volumes

    If both source and target of gpfs create volume from image operation
    are backed by gpfs storage use clone_image method for implementing
    the move of image data to the new volume.

    The copy_image_to_volume method is used only if this is not true,
    and uses image_utils.fetch_to_raw to move image data to the new

    Fixes bug #1213248
