Is your feature request related to a problem? Please describe.
Currently, we only instrument the inbound/outbound RPC duration for client/server. It would be better if we also start instrumenting the inbound/outbound request/response sizes as we do for HTTP.
Describe the solution you'd like
I have a use case where I need to get the GRPC client request/response size metrics with similar attributes we have for RPC duration. I have already implemented this using ClientStreamTracer and an Interceptor for one of our services. Still, it would be great if it is available in Opentelemetry itself, and we can use it directly for all our services.
