Epic Template descriptions and documentation 

Epic Goal

• Add an nftables mode to upstream kube-proxy

Why is this important?

• We want to move OpenShift Networking to make better use of upstream components, and having an nftables-based kube-proxy mode would let us migrate ovn-kubernetes to use it for Service proxying, without regressing on control plane performance like we would if we used iptables kube-proxy.
• We will likely have to support openshift-sdn for some customers on RHEL 10, but RHEL 10 will not support iptables.
• Though not important to OpenShift, it is important to Red Hat that there be a non-iptables-based kube-proxy mode upstream, since the iptables mode will no longer be usable in RHEL 10 (and some RHEL users run non-OpenShift Kubernetes).
