[TRAFODION-1823] ESP idle timeout does not kick in, leading to too many ESPs on the system Close message from the master was not sent to ESP by the platform agnostic messaging layer in Trafodion. Fixed this bug and then ESP idle time works as expected.
ESP_IDLE_TIMEOUT can now be given as a CQD. Internally, it would be changed to SET SESSION DEFAULT and used by the IPC layer of Trafodion. ESP_IDLE_TIMEOUT is set to 30 minutes by default in the CQD too.
Added test in core/TESTRTS to test ESP_IDLE_TIMEOUT
