Bug description:
  [Impact]

  This SRU is a backport of
  https://review.opendev.org/c/openstack/neutron/+/892895 to the
  respective Ubuntu and UCA releases. The patch is merged to all
  respective upstream branches (master &
  stable/[u,v,w,x,y,z,2023.1(a)]).

  This SRU intends to add the missing 'uplink-status-propagation'
  extension to ML2/OVN. This extension is already present and working in
  ML2/OVS, and it is supported by ML2/OVN but the extension is somehow
  not added to ML2/OVN. The patch simply adds the missing extension to
  the ML2/OVN too.

  The impact of this is visible for the deployments migrating from
  ML2/OVS to ML2/OVN. The following command fails to work on ML2/OVN:

  ```
  openstack port create --network 8d30fb08-2c6a-42fd-98c4-223d345c8c4f --binding-profile trusted=true --enable-uplink-status-propagation --vnic-type direct aaa

  # BadRequestException: 400: Client Error for url:
  https://mycloud.example.com:9696/v2.0/ports, Unrecognized attribute(s)
  'propagate_uplink_status'

  ```

  The fix corrects this behavior by adding the missing extension.

  [Test Case]

  - Deploy a Focal/Yoga cloud:
      - ./generate-bundle.sh -s focal -r yoga --name test-focal-yoga-stack --run --ovn
      # After the dust settles
      - ./configure
      - source ./novarc
  - openstack port create --network <network-id> --binding-profile trusted=true --enable-uplink-status-propagation --vnic-type direct aaa
  - It should fail with "BadRequestException: 400: Client Error for url: https://mycloud.example.com:9696/v2.0/ports, Unrecognized attribute(s) 'propagate_uplink_status'"

  To confirm the fix, repeat the scenario and observe that the error
  disappears and port creation succeeds.

  [Regression Potential]
  The patch is quite trivial and should not affect any deployment negatively. The extension is optional and disabled by default.
