boolean	isDaemon()	Should this periodical be run as a daemon thread?
boolean	leaderOnly()	Determines if this periodical should run only on the leader node.
boolean	runsForever()	Defines if this thread should be called periodically or only once on startup.
boolean	startOnThisNode()	Start on this node? Useful to decide if to start the periodical based on local configuration.
