Client response for Server push requests

[supersaeyan]

Hi, nice work. I am new to gRPC. Found this project very helpful in understanding a lot of gRPC stuff in short time.

I want to design a system where a server can execute a server push request in a blocking fashion also i.e wait for a response from the client.

I think it would require a bidirectional stream, maybe move streaming response from subscribe request, into a separate bidirectional request, or just a unary request using the same context, in which the request is server response, and the response is server request but it seems too complicated.

Would like to know your thoughts, or any ideas.
