The following changes are needed.

1. Add a structure for MRP Parameters to PairingSession.h. Or, reuse ReliableMessageProtocolConfig.
2. Update CASESession::EstablishSession(), and CASESession::ListenForSessionEstablishment() to have an optional parameter for MRP Parameters.
3. Save the provided parameter as part of CASESession object.
4. In CASESession::SendSigma1(), CASESession::SendSigma2(), and CASESession::SendSigma2Resume(), if the optional MRP parameters were provided, include the values in the Sigma1 message as per spec TLV format.
5. On receive of these messages, check if the message has the optional TLV elements. If the values are there, extract and call SetMRPConfig() on CASESession object.
