We are not currently matching Windows node's kube-proxy with the kube-proxy used by Linux nodes. This is an issue in itself, but is made worse as in the future Windows kube-proxy patches will not be accepted into the release-x.y branches of o/k, as those branches are specific for kube-apiserver, kube-controller-manager, kube-scheduler, and kubelet. With kubelet possibly being moved out in the future as well.

We need to be building off the branches matching the pattern: `sdn-4.8-kubernetes-x.y.z`
Example

This should be done before the WMCO version matching with OCP 4.8 goes GA.

Acceptance criteria:

• The kube-proxy shipped with WMCO for 4.8 is built from the SDN branch
• All existing QE north-south networking regression tests should pass
