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.
