gRPC Examples using Gateway, and VirtualService

I managed to make the base case work with grpc_cli etc. However the authentication and RBAC logging and silent exception catching code inside envoy I think makes it a roll your own situation for production if you need to diagnose issues with running systems. I continue trying to make the istio gateway implementation work knowing we are in that situation. In part due my own ignorance, it has been a significant investment and I don’t see it ending anytime soon. Latest info at gRPC JWT Authentication silently failing in Istio.
