   default handler chain: h1,h2,h3
   when microservice-a invoke microservice-b, will execute h1->h2->h3
   in h2, invoke microservice-c, still will execute h1->h2->h3
   
   so, yes, it's a infinite loop.
   
   you can choose one of the solution:
   - give a special chain for microservice-c in microservice.yaml, eg:
   ```
     handler:
       chain:
         Consumer:
           default: h1,h2,h3
           service:
             microservice-c: h1,h3
   ```
   - do not invoke microservice-c in h2 when target is microservice-c 
   ```
       if (invocation.getMicroserviceName().equals("microservice-c")){
         invocation.next(asyncResp);
         return;
       }
   ```
