Now update-generated-proto-bindings rules all the api.pb.go generation. Running this shows no delta on the runtime.pb.go This exposes an issue in how protoc is called for protos that specify `go_package` which is fixed here. Not all of our protos specify that option (even though it is recommended), which will be fixed subsequently.
