CanUseEvictions uses Discovery API to find out if evictions are supported

func (*Evictor) EvictOrDeletePod

func (d *Evictor) EvictOrDeletePod(pod corev1.Pod) error

EvictOrDeletePod will evict Pod if policy API is available, otherwise deletes it. If disableEviction is true, we skip straight to the delete step NOTE: CanUseEvictions must be called prior to this

func (*Evictor) GetPodsForEviction

func (d *Evictor) GetPodsForEviction(nodeName string) (*PodDeleteList, []error)

GetPodsForEviction lists all pods on a given node, filters those using the default filters, and returns PodDeleteList along with any errors. All pods that are ready to be deleted can be obtained with .Pods(), and string with all warning can be obtained with .Warnings()
