title: How do I list only Watson IoT Platform services using 'bx service' or similar operations
body: <p>I'm trying to list out all the services of Watson IoT Platform, as deployed against a given Organisation and Space.</p>
  
  <p>Say, for example, I have 3 different Watson IoT Platform services deployed and now, when I use
  "bx service list"
  It lists all services, including Watson IoT Platform services.
  Now, if I know the name of my Watson IoT Platform service, then I can type in
  "bx service show iotf-service"</p>
  
  <p>Are you aware of BX SERVICE command or an equivalent REST API that I can leverage, to obtain the needed output?</p>
