When running clustered and monitoring on the cluster, it needs to take into
account generating the inactive flowfiles[1] in a cluster friendly way as well.
Currently each Node will generate a flowfile when the inactivity time hits.
Probably need to track in clustered state whether or not a marker has been sent.
