    [OVN] Sync QoS policies
    
    The tool "neutron-ovn-db-sync-util" now syncs the Neutron QoS policies
    with the OVN NB database. The tools reads the port and the floaiting IP
    QoS policies and creates the corresponding OVN QoS rules.
    
    The ovsdbapp library is bumped to version 1.15.0. This version updates
    the "QoSAddCommand" to allow register updates. If the OVN NB QoS
    register to be created is present in the DB and all parameters match,
    no transaction is commited to the DB.

Title:
  [OVN] Migration to OVN does not create the OVN QoS DB registers

Status in neutron:
  Fix Released

Bug description:
  After the OVN migration, the information about QoS in the neutron DB is correct:
  (overcloud) [stack@undercloud-0 ~]$ openstack network show 569b37f1-3dd4-402e-9244-d7fad1ec4804 -c qos_policy_id -f value
  85d22adf-fc02-4c6d-b17a-36183d206558
  (overcloud) [stack@undercloud-0 ~]$ openstack network qos policy show 85d22adf-fc02-4c6d-b17a-36183d206558 -c rules -f value
  [{'max_kbps': 1000, 'max_burst_kbps': 800, 'direction': 'egress', 'id': 'fd1fffa5-b3ae-4b24-ba81-dfce2cccbe17', 'qos_policy_id': '85d22adf-fc02-4c6d-b17a-36183d206558', 'type': 'bandwidth_limit'}, {'dscp_mark': 40, 'id': '49e3e48b-b9e1-4332-9756-603134ee25fa', 'qos_policy_id': '85d22adf-fc02-4c6d-b17a-36183d206558', 'type': 'dscp_marking'}]

  
  Wowever there is no QoS information in the OVN NBDB:
