    Update git submodules
    
    * Update cinder from branch 'master'
      - Merge "RBD: Run flatten in a different thread when cloning a volume"
      - RBD: Run flatten in a different thread when cloning a volume
    
        The current implementation of create_cloned_volume calls flatten
        directly, and this makes whole thread of cinder-volume blocked by that
        flatten call. This causes heartbeat timeout in RabbitMQ when cloning
        a volume with rbd backend.
    
        This patch makes sure that flatten is executed in a different thread,
        to allow heatbeat thread to run while flattening a rbd image.
