### Feature

- Apiserver add a new flag --goaway-chance which is the fraction of requests that will be closed gracefully(GOAWAY) to prevent HTTP/2 clients from getting stuck on a single apiserver. 
  After the connection closed(received GOAWAY), the client's other in-flight requests won't be affected, and the client will reconnect. 
  The flag min value is 0 (off), max is .02 (1/50 requests); .001 (1/1000) is a recommended starting point.

* Add apiserver metric for number of requests dropped because of inflight limit. ([#58340](https://github.com/kubernetes/kubernetes/pull/58340), [@gmarek](https://github.com/gmarek))
* Add apiserver metric for current inflight-request usage. ([#58342](https://github.com/kubernetes/kubernetes/pull/58342), [@gmarek](https://github.com/gmarek))

- Kubeadm: make sure that a variety of API server requests are retried during "init", "join", "upgrade", "reset" workflows. Prior to this change some API server requests, such as, creating or updating ConfigMaps were "one-shot"...

  - Adds apiserver.latency.k8s.io/authorization annotation to the audit log to record the time spent authorizing slow requests. ([#130571](https://github.com/kubernetes/kubernetes/pull/130571), [@hakuna-matatah](https://github.com/hakuna-matatah)) [SIG Auth]

- Fixed bug in kubectl rollout history where only the latest revision was displayed when a specific revision was requested and an output format was specified ([#111093](https:...
