public class ClustersStatus
extends com.yahoo.component.AbstractComponent

A component which tracks the up/down status of any clusters which should influence the up down status of this container itself, as well as the separate fact (from config) that such clusters are present. This is a separate fact because we might know we have clusters configured but we don't have positive information that they are up yet, and in this case we should be down. This is a separate component which has no dependencies such that the status tracked in this will survive reconfiguration events and inform other components even immediately after a reconfiguration (where the true statue of clusters may not yet be available). This is multithread safe.
