    Fix list of DNS extensions supported by OVN
    
    The OVN driver needs to announce all DNS extensions as supported,
    otherwise the neutron server will reject them.
    
    Conflicts:
          neutron/common/ovn/extensions.py
    
    NOTE(zhhuabj): The conflict is due to having change 666562a258c in stable/Xena.

Title:
  Some DNS extensions not working with OVN

Status in Ubuntu Cloud Archive:
  Confirmed
Status in neutron:
  Fix Released
Status in neutron package in Ubuntu:
  New

Bug description:
  On a fresh devstack install with the q-dns service enable from the
  neutron devstack plugin, some features still don't work, e.g.:

  $ openstack subnet set private-subnet --dns-publish-fixed-ip
  BadRequestException: 400: Client Error for url: https://10.250.8.102:9696/v2.0/subnets/9f50c79e-6396-4c5b-be92-f64aa0f25beb, Unrecognized attribute(s) 'dns_publish_fixed_ip'

  $ openstack port create p1 --network private --dns-name p1 --dns-domain a.b.                                                                                  
  BadRequestException: 400: Client Error for url: https://10.250.8.102:9696/v2.0/ports, Unrecognized attribute(s) 'dns_domain'

  The reason seems to be that
  https://review.opendev.org/c/openstack/neutron/+/686343/31/neutron/common/ovn/extensions.py
  only added dns_domain_keywords, but not e.g. dns_domain_ports as
  supported by OVN
