This commit makes the user and roles poller use a self rescheduling runnable to schedule the next run of the poller rather than using scheduleWithFixedDelay. This is done because the pollers perform blocking I/O operations and everything using that thread pool method runs on the schedule thread and because of this, in certain situations this can lead to a deadlock which will prevent the cluster from forming.
