* Fixed the webhook admission plugin so that it works even if the apiserver and the nodes are in two networks (e.g., in GKE). ([#50476](https://github.com/kubernetes/kubernetes/pull/50476), [@caesarxuchao](https://github.com/caesarxuchao))

  As this code is still very new, it has not been heavily optimized yet;
  while it is expected to _eventually_ have better performance than the

### Bug or Regression

- Fixed a regression since 1.27.0 in scheduler framework when running score plugins. 
  The `skippedScorePlugins` number might be greater than `enabledScorePlugins`, 
  so when initializing a slice the cap(len(skippedScorePlugins) - len(enabledScorePlugins)) is negative, 

So, a request with a content type of `text/plain` containing JSON data would be accepted and the JSON data would be extracted.

message EphemeralContainer {
  // Ephemeral containers have all of the fields of Container, plus additional fields
  // specific to ephemeral containers. Fields in common with Container are in the
  // following inlined struct so than an EphemeralContainer may easily be converted
  // to a Container.
  optional EphemeralContainerCommon ephemeralContainerCommon = 1;

- Fix missing delete events on informer re-lists to ensure all delete events are correctly emitted and using the latest known object state, so that all event handlers and stores always reflect the actual apiserver state as best as possible ([#115900](https://github.com/kubernetes/kubernetes/pull/115900), [@odinuge](https://github.com/odinuge)) [SIG API Machinery]
