I am running a secure cluster and when I have "primary node only"
configured for the sending of the messages they never get sent. I believe this
is because the primary node has been the same since the processor was added and
it was never changed, therefore this method would never have gotten called.
I think this needs some way to know that the processor is running on the
primary node when it gets scheduled or initialized. I'm not sure if that is
possible at the moment though.
> update MonitorActivity processor to be cluster friendly

>
> This processor should be able to be used to monitor activity across the
> cluster. In its current state, alerting is based on activity of a single
> node, not the entire cluster.
> For example, in a 2 node cluster, if system A is getting data from a given
> flow and system B is not, system B will alert for lack of activity even
> though the flow is functioning "normally".
> The ideal behavior would be fore an alert to be generated only if both
> systems did not see data in the specified time.
