Initial commit for kube-proxy HPC helm charts

[jsturtevant]

As discussed in sig-windows, the KPNG project is no longer actively maintained. In the future there may be other initiatives to break kube-proxy out of tree so I've tagged the repository (https://github.com/kubernetes-sigs/windows-service-proxy/tree/kpng-0.1.0) and removed the code in this PR and replaced it with some HPC docker files and helm charts.

For now we would like to have a more "official" version of the kube-proxy images in https://github.com/kubernetes-sigs/sig-windows-tools/tree/master/hostprocess

This improves upon those images:

• has a single image that is the "core" kube-proxy image that can be used for all scenarios. This is just pulled from kubernetes pre-built kube-proxy binaries.
• It also provides a helper container meant to be used as an init container that that can do the additional set up required by some CNI's and networks. (primarily vxlan networks.)
• provides a helm chart that makes it easy to deploy and wire up for various scenarios
