  <1> Specify the port number the gRPC is listening on.
  <2> Register the eureka service port to be the same as `grpc.port` so client will know where to send the requests to.
  <3> Specify the  registry URL, so the service will register itself with. 
  
  
  * Expose the gRPC service as part of Spring Boot Application.
