Get the RESTPP ID of the query itself

Add a new user defined function in ExprFunctions.hpp

inline string testEngineParamOutSide (EngineServiceRequest& request) {
  return request.requestid_.key();

Call this function in GSQL query like this

CREATE QUERY test_query_id() FOR GRAPH gsql_demo { 

	STRING result;

	result = testEngineParamOutSide(__ENGINE__REQUEST);
    PRINT result; 

Get response with what we need

    "result": "65538.RESTPP_1_1.1583397387123.N"

Use this RESTPP ID to find related logs on RESTPP, GSE, GPE
