type OrphanPodsCleaner added in v1.0.0 

type OrphanPodsCleaner interface {
	Clean(*v1alpha1.TidbCluster) (map[string]string, error)
}

OrphanPodsCleaner implements the logic for cleaning the orphan pods(has no pvc)

In scaling out and failover, we will try to delete the old PVC to prevent it from being used by the new pod. However, the PVC might not be deleted immediately in the apiserver because of finalizers (e.g. kubernetes.io/pvc-protection) and the statefulset controller may not have received PVC delete event when it tries to create the new replica and the new pod will be pending forever because no PVC to use. We need to clean these orphan pods and let the statefulset controller to create PVC(s) for them.
