Enhancement Description

• One-line enhancement description (can be used as a release note): PodDisruptionBudget is an API object that specifies the minimum number or percentage of replicas of a collection that must be up at a time, and/or the maximum eviction rate across the collection. Components that wish to eviction a pod subject to disruption budget use the /eviction subresource on pod; unlike a regular pod deletion, this operation may be rejected by the API server if the eviction would cause a disruption budget to be violated.
