    Fix handling ImageUnacceptable in create_volume

    In the create_volume flow ImageUnacceptable exceptions are
    not properly handled. _copy_image_to_volume can receive an
    ImageUnacceptable exception from copy_image_to_volume if fetch_to_raw
    is used. Currently the ImageUnacceptable exception is changed to
    a generic ImageCopyFailure exception which does not make the cause
    of the excpetion clear.

    This change adds handling and raising ImageUnacceptable exceptions
    in _copy_image_to_volume. It also adds the exception to
    no_reschedule_types as it doesn't make sense to keep retrying the
    copy if the image was found to be unacceptable.

    fixes bug 1209021
