If evicting a pod fails with an HTTP 239 Too Many Requests error, it means there is a PodDisruptionBudget that prevents the pod from being deleted. This can happen, for example, when draining a node that has Longhorn volumes attached, as Longhorn creates a PDB for its instance manager pods on such nodes. Longhorn will automatically remove the PDB once there are no workloads on that node that use its Volumes, so we must continue to evict other pods and try evicting the failed pods again later. This behavior mostly mimics what `kubectl drain` does to handle this same condition.
