Description of problem: If a subnet is created with a dns-nameserver of 0.0.0.0, instances have a dns entry "nameserver 0.0.0.0". It seems to not be what our doc says should happen. I think we need to backport this fix: https://review.opendev.org/c/openstack/neutron/+/822297 Thank you! Version-Release number of selected component (if applicable): OSP16.1 How reproducible: 100% Steps to Reproduce: 1. Set subnet with 0.0.0.0 nameserver 2.
