SNMP Alarms Release-58

The original requirement for communication alarms was to report when no peers can be contacted. This class was an attempt at a general approach that would be similar to that when a normal traffic load is present (without having to deal with the specifics of each protocol and the interactions with DNS to determine what all peers really are etc.). Rob and I discussed that we could adjust things in this class based on percentage loss, etc. going forward. I believe we agreed to keep it simple to start. I do not have a problem with a more sophisticated algorithm here if we spec. it out and update the requirements.
