[VOIPSEC] SNMP support for EventCorrelation/NetworkManagementSystems

I suspect if they are going to implement SNMP the message is getting out
there...

I would not even consider the alternatives unless there were SSL/TLS or SSH
support of some kind to protect the confidentiality of the traps and or
signaling as this can be valuable information to an attacker if it can be
gained.
