    In terms of package layout, I had thought the intent was to have generic 
code that could be used for any protocol in this package, while protobuf 
specific code would be under org.apache.geode.protocol.protobuf.*  All of the 
Result and OperationContext code is now protobuf specific.  Should it be moved?

>
> In the Protobuf serialization implementation, there are some refactorings we 
> want to make:
> * OperationHandlers take OperationRequest and OperationResponse message, not 
> the parent Request/Response Object
> * A generic flow needs to be implemented that all OperationHandlers follow. 
> No bespoke flows for any OperationHandlers... way too much maintenance
> * Use Functional semantics to configure the functionality to extract 
> OperationRequest from Request (per OperationHandler)
> * Use Functional semantics to configure the functionality to populate 
> OperationResponse in the relevant Response
> * Have generic Error Handling framework to populate "known" errors and error 
> codes
