func NewNodeStatusReconciler

func NewNodeStatusReconciler(
	c client.Client,
	log logr.Logger,
	prom prometheus.Registerer,
	resyncInterval,
	reconcileTimeout,
	linger time.Duration,
	ac alert.Cache,
) reconcile.Reconciler

NewNodeStatusReconciler returns a reconcile.Reconciler that will PATCH the subresource node/status with updates to NodeConditions from alerts specific to the node. As alerts are not known ahead, the NodeConditionType is prefixed with "AlertManager_" to allow the reconciler to distinguish NodeConditions it "owns" from those it does not. It will not modify non-"owned" NodeConditions.

NodeConditions created from a given alert have the provided structure:

    	NodeCondition{
		    Type:               "AlertManager_" + $labels.alertname
		    Status:             True - if firing,
		                        False if not firing,
		                        Unknown if alerts are unavailable
		    LastHeartbeatTime:  currentTime,
		    LastTransitionTime: currentTime if status changed,
		    Reason:             One of "AlertIsFiring", "AlertIsNotFiring", "AlertsUnavailable"
		    Message:            $annotations.summary if present
	    }

The linger option sets the minimum time a NodeCondition with a False Status will be retained. A NodeCondition that has been False for the entire linger duration will be removed from the node. Setting this to a zero duration disables this behavior.
