Backoff automatic reconnect interval

Browse Source 
Previously, offline nodes would be rechecked automatically on average every 45 seconds.  Extend this
to on average 180 seconds, to reduce ARP traffic significantly when there are a large volume of
undefined nodes.  The 'try to connect on open' behavior is retained, so this would mean a longer loss
of connectivity only in a background monitored session.
