RCB Resiliency: Dying gasp support through SNMP

We've introduced dying gasp feature support through SNMP in case of power failure scenarios. When a device detects a power failure, it sends SNMP traps to the network management system (NMS) during power failures. The device can send dying gasp packets to up to five servers for each notification type. 

This feature supports SNMPv1 and SNMPv2 but not SNMPv3 and is only available on AC power supplies. The hold time for dying gasp is 4 ms for a single AC power supply and doubles with two active AC power supplies.
