### Bug or Regression

- ## Changelog
  
  ### General
  - Fix priority expander falling back to a random choice even though there is a higher priority option to choose
  - Clone `kubernetes/kubernetes` in `update-vendor.sh` shallowly, instead of fetching all revisions

  Until then we'll register UpdateNodeTaint event for plugins that have NodeAdded event, but don't have UpdateNodeTaint event.
  It'd result in a bad impact on the requeuing efficiency though, a lot better than some Pods being stuck in the
  unschedulable pod pool. ([#122292](https://github.com/kubernetes/kubernetes/pull/122292), [@sanposhiho](https://github.com/sanposhiho)) [SIG Node, Scheduling, Storage and Testing]
