make url parsing in apiserver configurable
We have known cases where the attributes for a request are assigned differently. The kubelet is one example. This makes the value an interface, not a struct, and provides a hook for (non-default) users to override it.

oidc auth: make the OIDC claims prefix configurable
Add the following flags to control the prefixing of usernames and
groups authenticated using OpenID Connect tokens.
--oidc-username-prefix
--oidc-groups-prefix
```release-note
The OpenID Connect authenticator can now use a custom prefix, or omit the default prefix, for username and groups claims through the --oidc-username-prefix and --oidc-groups-prefix flags. For example, the authenticator can map a user with the username "jane" to "google:jane" by supplying the "google:" username prefix.
```

Fixes kubernetes/kubernetes#29271: accept prefixed namespaces
**What this PR does / why we need it**: `kubectl get namespaces -o name` outputs the names of all namespaces, prefixed with `namespaces/`. This changeset allows these namespace names to be passed directly back in to `kubectl` via the `-n` flag without reprocessing them to remove `namespaces/`.

Add flag "--include-uninitialized" to kubectl annotate, apply, edit-last-applied, delete, describe, edit, get, label, set. "--include-uninitialized=true" makes kubectl commands apply to uninitialized objects, which by default are ignored if the names of the objects are not provided. "--all" also makes kubectl commands apply to uninitialized objects. Please see the [initializer](https://kubernetes.io/docs/admin/extensible-admission-controllers/) doc for more details.

Unify initializer name validation
Unify the validation rules on initializer names. Fix https://github.com/kubernetes/kubernetes/issues/51843.
```release-note
Action required: validation rule on metadata.initializers.pending[x].name is tightened. The initializer name needs to contain at least three segments separated by dots. If you create objects with pending initializers, (i.e., not relying on apiserver adding pending initializers according to initializerconfiguration), you need to update the initializer name in existing objects and in configuration files to comply to the new validation rule.

Add the possibility to set return values for the FakeDiscovery implementation
**What this PR does / why we need it**:
As an user of the fake clientset (with the fake discovery), I want to be able to set the fake server's version on demand like this for example:
```go
func TestFakingServerVersion(t *testing.T) {
client := fakeclientset.NewSimpleClientset()
fakeDiscovery, ok := client.Discovery().(*fakediscovery.FakeDiscovery)
if !ok {
t.Fatalf("couldn't convert Discovery() to *FakeDiscovery")
}
testGitCommit := "v1.0.0"
fakeDiscovery.FakedServerVersion = &version.Info{
GitCommit: testGitCommit,
}
sv, err := client.Discovery().ServerVersion()
if err != nil {
t.Fatalf("unexpected error: %v", err)
}
if sv.GitCommit != testGitCommit {
t.Fatalf("unexpected faked discovery return value: %q", sv.GitCommit)
}
}
```
This PR makes that possible, in wait for a more sophisticated FakeDiscovery implementation generally.

to manual installation or automatic installation.
- It is good to know how many handlers are installed to see whether
code changes are taking effect.

Mount propagation in kubelet
Together with #45724 it implements mount propagation as proposed in https://github.com/kubernetes/community/pull/659
There is:
- New alpha annotation that allows user to explicitly set propagation mode for each `VolumeMount` in pod containers (to be replaced with real `VolumeMount.Propagation` field during beta) + validation + tests. "Private" is the default one (= no change to existing pods).
I know about proposal for real API fields for alpha feature in https://docs.google.com/document/d/1wuoSqHkeT51mQQ7dIFhUKrdi3-1wbKrNWeIL4cKb9zU/edit, but it seems it's not implemented yet. It would save me quite lot of code and ugly annotation.
- Updated CRI API to transport chosen propagation to Docker.
- New `kubelet --experimental-mount-propagation` option to enable the previous bullet without modifying types.go (worked around with changing `KubeletDeps`... not nice, but it's better than adding a parameter to `NewMainKubelet` and removing it in the next release...)
```release-note
kubelet has alpha support for mount propagation. It is disabled by default and it is there for testing only. This feature may be redesigned or even removed in a future release.
