Hello. I have a project where I would like to use grpc with go. I have protobuf models already. When I add services to the .proto files and run

./pants gen

I get valid output but without the services. After scanning the go documentation for grpc I saw that you need to use a protoc plugin to build the service definition like this taken from the go grpc quickstart

$ protoc -I helloworld/ helloworld/helloworld.proto --go_out=plugins=grpc:helloworld

Is there any way to invoke these protoc plugins from pants? I have scanned through the options and advanced options for gen but am not finding anything useful.
