in a ~2.5h CSIT job, the below message is seen 1600+ times.

47217:2018-12-10T17:22:00,630 | INFO  | ofppool-15       | SystemNotificationsListenerImpl  | 386 - org.opendaylight.openflowplugin.impl - 0.8.0 | Switch Idle state occurred, node=/10.30.170.99:44168|auxId=0

if the root cause event is expected and happening reasonably 1600+ times needs to be
understood first. If so, we should remove that log entirely or lower it's level to DEBUG or
higher so that it's not spamming a production environment with duplicate messages.

Unless I'm not seeing the true value in the message.
