Statistics manager loses threads to uncaught exceptions

During testing we have encountered the following:

2014-05-14 09:46:42.603 PDT [request-monitor] ERROR o.o.c.l.b.i.UncaughtExceptionPolicy - Thread Thread[request-monitor,5,main] died because of an uncaught exception
java.lang.IllegalArgumentException: Session for the cookie is invalid. Reason: the switch has been recently disconnected OR inventory provides outdated information.

While it is true OFP should not throw a runtimeexception here, the statistics manager should not kill its thread. Simple solution is to catch RuntimeException (except InterruptedException) in StatisticsRequestScheduler.run(), log it and continue on.
