    Revert "nova shared storage: rbd is always shared storage"

    This reverts commit 05b7f63a42e3512da6fe45d2e6639fb47ed8102b.

    The _is_storage_shared_with method is specifically checking if the
    instance directory is shared. It is not checking if the actual instance
    disks are shared and as a result assumptions cannot be made based on the
    value of images_type.
