- E2e: tests can now register callbacks with `ginkgo.BeforeEach`, `ginkgo.AfterEach` or `ginkgo.DeferCleanup` directly after creating a framework instance and are guaranteed that their code is called after the framework is initialized and before it gets cleaned up. `ginkgo.DeferCleanup`...

  **How can I migrate?**
  
  For backward compatibility, nil `QueueingHintFn` is treated as always returning QueueAfterBackoff. 
  So, if you want to just keep the existing behavior, you can register `ClusterEventWithHint` with no `QueueingHintFn` in it.

  It's definitely not something expected for plugin developers,
  and we're trying to eventually remove preCheck completely to fix this.
  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
