When Shutdown was called, delivery of each pending event would still be retried
12 times with a delay of ~10s between each retry. In apiserver integration
tests that caused the goroutine to linger long after the corresponding
apiserver of the test was shut down.

This improves performance of the text formatting and ktesting.
Because ktesting no longer buffers messages by default, one unit
test needs to ask for that explicitly.

The kube-apiserver validation expects the Count of an EventSeries to be
at least 2, otherwise it rejects the Event. There was is discrepancy
between the client and the server since the client was iniatizing an
EventSeries to a count of 1.
According to the original KEP, the first event emitted should have an
EventSeries set to nil and the second isomorphic event should have an
EventSeries with a count of 2. Thus, we should matcht the behavior
define by the KEP and update the client.
Also, as an effort to make the old clients compatible with the servers,
we should allow Events with an EventSeries count of 1 to prevent any
unexpected rejections.

The path module has a few different functions:
Clean, Split, Join, Ext, Dir, Base, IsAbs. These functions do not
take into account the OS-specific path separator, meaning that they
won't behave as intended on Windows.
For example, Dir is supposed to return all but the last element of the
path. For the path "C:\some\dir\somewhere", it is supposed to return
"C:\some\dir\", however, it returns ".".
Instead of these functions, the ones in filepath should be used instead.

This creates go.work and enables Go Workspaces. This is a file that
includes info on k/k and all the staging modules.
This depends on go 1.22 and setting FORCE_HOST_GO=true (for kube
scripts, which try to be hermetic).
Make this part of the normal update/verify sequence.
The top-level go.work file contains no replace statements. Instead, the
replace statements in the individual go.mod files are used. For this to
work, replace statements in the individual go.mod files have to be
consistent.
hack/tools has different dependencies and can't be in the main
workspace, so this adds a go.work just for that. Without this, go tries
to consider all deps in all modules and pick one that works for all.
This is problematic because there are so many of them that it is
difficult to manage.
Likewise for k8s.io/code-generator/examples and
k8s.io/kms/internal/plugins/_mock - add trivial go.work files.
For example k/k depends on an older version of a lib that gloangci-lint
needs (transitively) and it breaks.
This also updates vendor (needed to make go happy), and removes
vendor'ed symlinks. This breaks a LOT of our build tools, which will be
fixed subsequently.
Result: `go` commands work across modules:
Before:
```
$ go list ./pkg/proxy/iptables/ ./staging/src/k8s.io/api/core/v1/
main module (k8s.io/kubernetes) does not contain package k8s.io/kubernetes/staging/src/k8s.io/api/core/v1
$ go build ./pkg/proxy/iptables/ ./staging/src/k8s.io/api
main module (k8s.io/kubernetes) does not contain package k8s.io/kubernetes/staging/src/k8s.io/api
$ go test ./pkg/proxy/iptables/ ./staging/src/k8s.io/api
main module (k8s.io/kubernetes) does not contain package k8s.io/kubernetes/staging/src/k8s.io/api
```
After:
```
$ go list ./pkg/proxy/iptables/ ./staging/src/k8s.io/api/core/v1/
k8s.io/kubernetes/pkg/proxy/iptables
k8s.io/api/core/v1
$ go build ./pkg/proxy/iptables/ ./staging/src/k8s.io/api
$ go test ./pkg/proxy/iptables/ ./staging/src/k8s.io/api
ok k8s.io/kubernetes/pkg/proxy/iptables 0.360s
ok k8s.io/api 2.302s
```
Result: `make` fails:
```

This fixes the following warning (error?) in the apiserver:
E0126 18:10:38.665239 16370 fieldmanager.go:210] "[SHOULD NOT HAPPEN] failed to update managedFields" err="failed to convert new object (test/claim-84; resource.k8s.io/v1alpha1, Kind=ResourceClaim) to smd typed: .status.reservedFor: element 0: associative list without keys has an element that's a map type" VersionKind="/, Kind=" namespace="test" name="claim-84"
The root cause is the same as in e50e8a0c919c0e02dc9a0ffaebb685d5348027b4:
nothing in Kubernetes outright complains about a list of items where the item
type is comparable in Go, but not a simple type. This nonetheless isn't
supposed to be done in the API and can causes problems elsewhere.
For the ReservedFor field, everything seems to work okay except for the
warning. However, it's better to follow conventions and use a map. This is
possible in this case because UID is guaranteed to be a unique key.
Validation is now stricter than before, which is a good thing: previously,
two entries with the same UID were allowed as long as some other field was
different, which wasn't a situation that should have been allowed.

If gomega.Eventually/Consistently run into a situation where it observes some
state of e.g. a pod which does not satisfy the condition and then further
polling fails with API server errors, gomega will report both the most recent
pod state and API error instead of just the API error.

It seems valuable to be able to provide hand-written docs for these
first-level directories, and if don't want them, the generated doc.go
files are not actually very helpful.
This commit also adds new doc.go files for client-go listers/ and
informers/.
Kubernetes-commit: 95bf7b0afe9dd6a0f00125b1d290514a23e778e2
While refactoring the backoff manager to simplify and unify the code
in wait a race condition was encountered in
TestSharedInformerWatchDisruption. The new implementation failed
because the fake clock was not propagated to the backoff managers
when the reflector was used in a controller. After ensuring the
mangaers, reflector, controller, and informer shared the same
clock the test needed was updated to avoid the race condition by
advancing the fake clock and adding real sleeps to wait for
asynchronous propagation of the various goroutines in the controller.
Due to the deep structure of informers it is difficult to inject
hooks to avoid having to perform sleeps. At a minimum the FakeClock
interface should allow a caller to determine the number of waiting
timers (to avoid the first sleep).
Kubernetes-commit: 91b3a81fbd916713afe215f7d701950e13a02869
Add a "lazy" type to track when an update is needed. It uses a nested
locking technique to avoid extra evaluation calls.
