### Bug or Regression

- Avoid GCE API calls when initializing GCE CloudProvider for Kubelets.

### Feature

- Added 3 new metrics for monitoring async API calls in the scheduler when the `SchedulerAsyncAPICalls` feature gate was enabled:
    - `scheduler_async_api_call_execution_total`: tracks executed API calls by call type and result (success/error)
    - `scheduler_async_api_call_duration_seconds`: histogram of API call execution duration by call type and result

* [Alpha] The Kubernetes API server now supports the ability to break large LIST calls into multiple smaller chunks. A client can specify a limit to the number of results to return. If more results exist, a token is returned that allows the client to continue the previous list call repeatedly until all results are retrieved.  The resulting list is identical to a list call that does not perform chunking, thanks to capabilities provided by etcd3.  This allows the server to use...

- Fixed two regressions introduced by the `PodDisruptionConditions` feature (on by default in 1.26):
  - pod eviction API calls returned spurious precondition errors and required a second evict API call to succeed

  - Speed up binpacking by reducing the number of PreFilter calls (call once per pod instead of #pods*#nodes times)
  - Speed up finding unneeded nodes by 5x+ in very large clusters by reducing the number of PreFilter calls
  - Expose `--max-nodes-total` as a metric
  - Errors in `IncreaseSize` changed from type `apiError` to `cloudProviderError`

### Client
* Use Prometheus instrumentation conventions ([#36704](https://github.com/kubernetes/kubernetes/pull/36704), [@fabxc](https://github.com/fabxc))
* Clients now use the `?watch=true` parameter to make watch API calls, instead of the `/watch/` path prefix ([#41722](https://github.com/kubernetes/kubernetes/pull/41722), [@liggitt](https://github.com/liggitt))

- Added alpha support for asynchronous Pod preemption.
  When the `SchedulerAsyncPreemption` feature gate is enabled, the scheduler now runs API calls to trigger preemptions asynchronously for better performance. ([#128170](https://github.com/kubernetes/kubernetes/pull/128170), [@sanposhiho](https://github.com/sanposhiho)) [SIG Scheduling and Testing]
