* kubeadm: clean up exited containers and network checkpoints ([#43836](https://github.com/kubernetes/kubernetes/pull/43836), [@yujuhong](https://github.com/yujuhong))

  // StartTime before the system will actively try to mark it failed and kill associated containers.
  // Value must be a positive integer.
  // +optional
  optional int64 activeDeadlineSeconds = 5;

  // Set DNS policy for the pod.
  // Defaults to "ClusterFirst".
  // Valid values are 'ClusterFirstWithHostNet', 'ClusterFirst', 'Default' or 'None'.

* Add validation for CustomResources via JSON Schema. ([#47263](https://github.com/kubernetes/kubernetes/pull/47263), [@nikhita](https://github.com/nikhita))
* enqueue a sync task to wake up jobcontroller to check job ActiveDeadlineSeconds in time ([#48454](https://github.com/kubernetes/kubernetes/pull/48454), [@weiwei04](https://github.com/weiwei04))
