    allow manila ports to do multiple port binding for ML2
    
    Similar to Nova live migration
    (see https://review.opendev.org/c/openstack/neutron/+/414251/74/neutron/plugins/ml2/plugin.py#2005)
    Manila wants to do share live migration, and needs to modify its ports in a
    similar way: issue port binding upfront to determine the segmentation id in
    the target network segment.

Title:
  [RFE] Provide Port Binding Information for Manila Share Server Live
  Migration

Status in neutron:
  Fix Released

Bug description:
  Hi,

  similar to Nova, where this feature is described by
  https://review.opendev.org/c/openstack/neutron-specs/+/309416/ and
  implemented around https://bugs.launchpad.net/neutron/+bug/1580880,
  there is a Share Server Live Migration feature in Manila (see
  https://review.opendev.org/c/openstack/manila-specs/+/735970), that
  would benefit of this port binding extension.

  If the migration target is in a different network segment, Manila
  needs to be able to do the port binding before the actual migration
  starts. This is relevant for the neutron bind driver in manila, that
  was added to support hierarchical port binding in
  https://review.opendev.org/c/openstack/manila-specs/+/315985

  Best regards,
  Maurice
