Remarks
A ClientInvokeCallback ia a global pre-call interceptor. Synchronous callback made just before a message is about to be constructed and sent by a client to a grain. This call will be made from the same thread that constructs the message to be sent, so any thread-local settings such as Orleans.RequestContext will be picked up. The action receives an InvokeMethodRequest with details of the method to be invoked, including InterfaceId and MethodId, and a IGrain which is the GrainReference this request is being sent through This callback method should return promptly and do a minimum of work, to avoid blocking calling thread or impacting throughput.
