[Bug 1947127] Re: Some DNS extensions not working with OVN

[Hua Zhang]

** Description changed:

+ [Impact]
+ 
  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.                                                                                  
+ $ 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
+ 
+ [Test Case]
+ 
+ Create a normal OpenStack neutron test environment to see if we can
+ successfully run the following commands:
+ 
+ openstack subnet set private_subnet --dns-publish-fixed-ip
+ openstack port create p1 --network private --dns-name p1 --dns-domain a.b.
+ 
+ [Regression Potential]
+ 
+ The fix has merged into the upstream stable/xena branch [1], here's just
+ SRU into the 19.1.0 branch of UCA xena, so it is a clean backport and
+ might be helpful for deployments migrating to OVN.
