- Introduces new alpha functionality to the reflector, allowing user to enable API streaming.
  
  To activate this feature, users can set the `ENABLE_CLIENT_GO_WATCH_LIST_ALPHA` environmental variable.
  It is important to note that the server must support streaming for this feature to function properly.
  If streaming is not supported by the server, the reflector will revert to the previous method

- Implemented API for streaming for the `etcd` store implementation.
  When `sendInitialEvents ListOption` is set together with `watch=true`, it begins the watch stream with synthetic init events followed by a synthetic `Bookmark`, after which the server continues streaming events.

- Moved `k8s.io/kubernetes/pkg/kubelet/cri/streaming` package to `k8s.io/kubelet/pkg/cri/streaming`. ([#118253](https://github.com/kubernetes/kubernetes/pull/118253), [@saschagrunert](https://github.com/saschagrunert)) [SIG Node, Release and Security]

  // MatchLabelKeys is a set of pod label keys to select the pods over which
  // spreading will be calculated. The keys are used to lookup values from the
  // incoming pod labels, those key-value labels are ANDed with labelSelector
  // to select the group of existing pods over which spreading will be calculated
  // for the incoming pod. The same key is forbidden to exist in both MatchLabelKeys and LabelSelector.
