yatinkarel 6713cdaccd [OVN] Correctly set dns_server in dhcpv4/v6 options ... When ovn/dns_servers consist of IPv6 dns nameservers, it was getting added to IPv4 dhcp options also, and due to this an invalid nameserver(last 4 octets of an IPv6 address) is set in the instances. This patch filters IPv4/IPv6 dns nameservers and set dhcpv4/dhcpv6 options accordingly. Also when dns_nameservers are not set for IPv6 subnets, get those from ovn/dns_servers config or system nameservers just like it's done with the IPv4 subnets. Updated get_system_dns_resolvers to pick both IPv4/IPv6 valid ips, this also requires bump of oslo.utils minimum version to 4.8.0 to use strict option for IPv4[1]. Additionally fix some unit tests which were setting IPv4 dns nameservers on the IPv6 subnets, this is not allowed with api. [1] https://github.com/openstack/oslo.utils/commit/3288539 Conflicts: lower-constraints.txt requirements.txt [Stable Only] Since Neutron stable policy do not allow bumping of minimum version of a requirement in stable releases, so doing a partial backport by not backporting requirements.txt changes and updated get_system_dns_resolvers to work with older version of oslo.utils.
