Failure reporting in AA

Failure reporting in AA is performed in similar fashion as in ESM.

Instead of Charging-Rule-Report AVP, the ADC-Rule-Report is used:

ADC-Rule-Report ::= < AVP Header: 1097 >
                        *[ ADC-Rule-Name ]
                         [ PCC-Rule-Status ]
                         [ Rule-Failure-Code ]
                        *[ AVP ]
