Kubernetes Submit Queue 877ee91930 Merge pull request #51082 from caesarxuchao/repair-null-pending-initializer 
Automatic merge from submit-queue (batch tested with PRs 50953, 51082)

Fix mergekey of initializers; Repair invalid update of initializers

Fix https://github.com/kubernetes/kubernetes/issues/51131

The PR did two things to make parallel patching `metadata.initializers.pending` possible:
* Add mergekey to initializers.pending
* Let the initializer admission plugin set the `metadata.intializers` to nil if an update makes the `pending` and the `result` both nil, instead of returning a validation error. Otherwise if multiple initializer controllers sending the patch removing themselves from `pending` at the same time, one of them will get a validation error.


```release-note
The patch to remove the last initializer from metadata.initializer.pending will result in metadata.initializer to be set to nil (assuming metadata.initializer.result is also nil), instead of resulting in an validation error.
```

External Repository Staging Area

This directory is the staging area for packages that have been split to their own repository. The content here will be periodically published to respective top-level k8s.io repositories.

Repositories currently staged here:

The code in the staging/ directory is authoritative, i.e. the only copy of the code. You can directly modify such code.

Using staged repositories from Kubernetes code

Kubernetes code uses the repositories in this directory via symlinks in the vendor/k8s.io directory into this staging area. For example, when Kubernetes code imports a package from the k8s.io/client-go repository, that import is resolved to staging/src/k8s.io/client-go relative to the project root:

// pkg/example/some_code.go
package example

import (
  "k8s.io/client-go/dynamic" // resolves to staging/src/k8s.io/client-go/dynamic
)

Once the change-over to external repositories is complete, these repositories will actually be vendored from k8s.io/<package-name>.
