	// skipped because the node it is scheduled to didn't set its annotation in
	// time, we don't want to have to wait 12hrs before processing the pod
	// again.
	// Luckily https://github.com/kubernetes/kubernetes/issues/23394 is being
	// worked on and will split resync in to resync and relist. Once that
	// happens the resync period can be set to something much faster (30
	// seconds).
	// If that issue is not resolved in time, then this controller will have to
	// consider some unappealing alternate options: use a non-shared informer
	// and set a faster resync period even if it causes relist, or requeue
	// dropped pods so they are continuously processed until it is accepted or
	// deleted (probably can't do this with sharedInformer), etc.
