    * Update nova from branch 'master'
      - Merge "compute: Lock by instance.uuid lock during swap_volume"
      - compute: Lock by instance.uuid lock during swap_volume
    
        The libvirt driver is currently the only virt driver implementing swap
        volume within Nova. While libvirt itself does support moving between
        multiple volumes attached to the same instance at the same time the
        current logic within the libvirt driver makes a call to
        virDomainGetXMLDesc that fails if there are active block jobs against
        any disk attached to the domain.
    
        This change simply uses an instance.uuid based lock in the compute layer
        to serialise requests to swap_volume to avoid this from being possible.
