Description

There is no way to listen to all calls made on GrpcClient . Only low level interceptors on OkHttp client are possible.
A listener should report method name and deserialized message. That would make debugging easier and enable creating a plugin for flipper
flipper-grpc-plugin was made for grpc-java implementation.

Research direction

Start at GrpcClient and review how the existing low-level OkHttp interceptors observe calls. Define a listener that reports the method name and deserialized message, with support for the Flipper plugin use case; done means callers can observe all GrpcClient calls with that information.
