Move member from obd2_signals_t class to
active_diagnostic_request_t (adr)class. It's more logical to have them here as call about incoming diagnostic CAN messages are made against adr class not obd2_signal_t that it's a subset of diagnostic messages. It's made to handle obd2 requests as well as normal UDS diagnostic request for constructor proprietary diagnostic signals.
