Bug 1820822: sdn: ignore new ovn-kubernetes OVS internal port names ovn-k8s-gw0 and ovn-k8s-mp0

[dcbw]

To prevent racing with NetworkManager's OVS plugin resulting in IP addresses sometimes being cleared from the OVS internal ports that openshift-sdn and ovn-kubernetes set up, we must tell NM to ignore those ports.

That said, I still think we should do this in a better way; something like an extended attribute in /sysfs or something that tells the host network software to ignore the interface because it's going to be "owned" by something else.

Yeah, that's a larger conversation and it's been discussed upstream in the kernel periodically. But AFAIK we don't have that kind of "owner" tag for interfaces yet.
