* `kubectl wait` is a new command that allows waiting for one or more resources to be deleted or to reach a specific condition. It adds a `kubectl wait --for=[delete|condition=condition-name] resource/string` command. ([#64034](https://github.com/kubernetes/kubernetes/pull/64034), [@deads2k](https://github.com/deads2k))

  * User-written controllers that reuse names of pod objects should evaluate this change.
  * When deleting an object with `kubectl delete ... --grace-period=0`, the client will
    begin a graceful deletion and wait until the resource is fully deleted.  To force
    deletion immediately, use the `--force` flag. This prevents users from accidentally
    allowing two Stateful Set pods to share the same persistent volume which could lead to data
