Add neighbor lifecycle management.

 * Made PIMNeighbor mostly immutable (apart from updatable timestamp)
 * Equals and hashCode for PIMNeighbor
 * Remove neighbor when we see a HELLO with holdTime==0
 * Periodic task to time out neighbors who haven't sent a HELLO in a while
 * Added a CLI command to view PIM neighbors
