Basic implementation of ShClientSession - can be one time - for UDR,PUR and
constant for SNR-PNR pair, in case when SNA contains response code from range
different than 2001-2004(success codes) user is responsible for maintaing
state - releasing etc, same goes if result code is contained
Experimental-Result AVP
If ShSession moves to ShSessionState.TERMINATED - it means that no further
messages can be received via it and it should be discarded.
