Also feels like this should be in the next CL. Also, if we are trying to use the
same gRPC service as HeliumTransport, we should use the message definition at
go/helium-transport.

This matches the non-Chromium proto as is for now. When we 'upgrade' the other
proto, I will make a change here as well.

 
 option optimize_for = LITE_RUNTIME;
 
 package blimp;
 
-message EmptyMessage {}
+message HeliumWrapper {
+  bytes serialized_helium_message = 1;
+}

+service GrpcService {

This name seems too generic, as it could easily be confused for a GRPC base
class.
