Review Comment:
   Most LIKELY, the interceptor is NULL for a non-interception policy. 
   So I think we could first check nullity of interceptor and also error_code 
and error_text will be in smaller scope, for better performance.
   ```
   if (!interceptor) {
     return true;
   }
   
   int error_code = 0;
   std::string error_text;
   if (!interceptor->Accept(cntl, error_code, error_text)) {
           cntl->SetFailed(error_code, "Reject by Interceptor: %s", 
error_text.c_str());
           return false;
    }
   
   return true;
   
   ```
