Interface ServiceCaller<S,R>

Type Parameters:
S - the type of the protobuf Service you want to call.
R - the type of the return value.
Functional Interface:
This is a functional interface and can therefore be used as the assignment target for a lambda expression or method reference.
@Public @FunctionalInterface public interface ServiceCaller<S,R>
Delegate to a protobuf rpc call.

Usually, it is just a simple lambda expression, like: 

 (stub, controller, rpcCallback) -> {
   XXXRequest request = ...; // prepare the request
   stub.xxx(controller, request, rpcCallback);
 }
And if already have the request, the lambda expression will be: 
 (stub, controller, rpcCallback) -> stub.xxx(controller, request, rpcCallback)
