gRPC support between Code Engine applications

Considering gRPC is well-defined and used thouroughly in cloud deployments from small startups to global scaled services, it makes little sense that IBM Cloud Engine does not support this type of microservice communications. My company is using a combination of Protobufs/gRPC and Event-based microservices communications which was working well in a regular k8s cluster, but with our intended transfer to Code Engine we had to rewrite gRPC component to regular REST API (which is not ideal).

Suggestion: the gateway/proxy before deployed applications and jobs should support the content type of gRPC. And not enforce security when only private networking is set.
