Interoperatibility with SNMP-aware management clients

As of Rhino version 2.2, Rhino includes an SNMP agent, for interoperability with external SNMP-aware management clients. The Rhino SNMP agent provides a read-only view of Rhino's statistics (through SNMP polling), and supports sending SNMP notifications for platform events to an external monitoring system.

Rhino 2.3 adds basic support for SNMP v3.

In a clustered environment, individual Rhino nodes will run their own instances of the SNMP agent, so that statistics and notifications can still be accessed in the event of node failure. When multiple Rhino nodes exist on the same host, Rhino assigns each SNMP agent a unique port, so that the SNMP agents for each node can be distinguished. The port assignments are also persisted by default, so that in the event of node failure or cluster restart the Rhino SNMP agent for a given node will resume operation on the same port it was using previously.
