// TolerateUnreadyEndpointsAnnotation is an annotation on the Service denoting if the endpoints
// controller should go ahead and create endpoints for unready pods. This annotation is
// currently only used by StatefulSets, where we need the pod to be DNS
// resolvable during initialization and termination. In this situation we
// create a headless Service just for the StatefulSet, and clients shouldn't
// be using this Service for anything so unready endpoints don't matter.
// Endpoints of these Services retain their DNS records and continue
// receiving traffic for the Service from the moment the kubelet starts all
// containers in the pod and marks it "Running", till the kubelet stops all
// containers and deletes the pod from the apiserver.
// This field is deprecated. v1.Service.PublishNotReadyAddresses will replace it
// subsequent releases. It will be removed no sooner than 1.13.
