- Fixed a `1.27` scheduling regression that `PostFilter` plugin may not function if previous `PreFilter` plugins return `Skip`. ([#119769](https://github.com/kubernetes/kubernetes/pull/119769), [@Huang-Wei](https://github.com/Huang-Wei))

- Scheduler no longer runs the plugin's `Filter` method when its `PreFilter` method returned a Skip status.
  In other words, your `PreFilter`/`Filter` plugin can return a Skip status in `PreFilter` if the plugin does nothing in Filter for that Pod.
  Scheduler skips `NodeAffinity` Filter plugin when `NodeAffinity` Filter plugin has nothing to do with a Pod.

- The scheduler retries scheduling Pods rejected by PreFilterResult (PreFilter plugins) more appropriately; it now takes events registered in those rejector PreFilter plugins into consideration.

rejected via `UnschedulableAndUnresolvable`. Consequently, these nodes are excluded from the candidates for the preemption process. Additionally, this update corrects how the scheduling framework handles the Unschedulable status from PreFilter. Previously, if PreFilter returned `Unschedulable`, it could lead to an unexpected abortion in the preemption process, which shouldn't occur in the default scheduler but might occur in schedulers with custom plugins.

  - Clone `kubernetes/kubernetes` in `update-vendor.sh` shallowly, instead of fetching all revisions
  - 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`
