this afternoon will will add another "back-End" microservice
        so we will have 3 services
          Composite
          API
          Weather will call an open-source WebService to get the weather
          
          the correlation id is SPECIFIC flow thru the Microservice infrastructure
          
          
          Client ->  Composite (Adds the Correlation Id)
                        Composite -> the Api service passing Correlation Id
                                      and gets an answer
                        Composite -> the Weather service passing Correlation Id
                                      and gets an answer
                        Composite build the respose to the Client out of the parts
                          it got from the "back-end" services
                          it removes the Correlation Id so the client 
                          does not see it
                          
              If I add an Edge Server, this Edge Service may or may not be the 
              Composite server, the Edge Server my do:
                Security
                Logging 
                create the Correlation Id
                look up the IP address/Port of the composite server
