Right now if a JWT for an unknown issuer, for any subject hits the
serviceaccount token authenticator, we return a errors as if the token
was meant for us but we couldn't find a key to verify it. We should
instead return nil, false, nil.
This change helps us support multiple service account token
authenticators with different issuers.

Never let cluster-scoped resources skip webhooks
Fix#57964
This allows user write webhooks for cluster-scoped custom resources.
We still need to figure out how to selectively exempt cluster-scoped resources from webhooks to avoid bootstrapping deadlocks. For now, if a deadlock occurs, users can work around by first deleting the webhook configuration, then rebooting the webhook, then re-enabling the webhook configuration.
```release-note
Bug fix: webhooks now do not skip cluster-scoped resources
Action required: Before upgrading your Kubernetes clusters, double check if you had configured webhooks for cluster-scoped objects (e.g., nodes, persistentVolume), these webhooks will start to take effect. Delete/modify the configs if that's not desirable.
```
This moves the equivalence hashing code from
algorithm/predicates/utils.go to core/equivalence_cache.go.
In the process, making the hashing function and hashing function factory
both injectable dependencies is removed.
This changes the equivalence class hashing function to use as inputs all
the Pod fields which are read by FitPredicates. Before we used a
combination of OwnerReference and PersistentVolumeClaim info, which was
a close approximation. The new method ensures that hashing remains
correct regardless of controller behavior.
The PVCSet field can be removed from equivalencePod because it is
implicitly included in the Volume list.
Tests are now broken.
Equivalence cache for CheckNodeConditionPred becomes invalid when
Node.Spec.Unschedulable changes. This can happen even if
Node.Status.Conditions does not change, so move the logic around.
This logic is covered by integration test
"test/integration/scheduler".TestUnschedulableNodes but equivalence
cache is currently skipped when test pods have no OwnerReference.

[GCE cloud provider] Ensure hosts are updated in EnsureLoadBalancer()
**What this PR does / why we need it**:
From https://github.com/kubernetes/kubernetes/issues/56527, the `EnsureLoadBalancer()` implementation in GCE external LB doesn't always update the hosts (nodes). This PR makes it to do so.
Previously, the only situation where `ensureExternalLoadBalancer()` will not update hosts is when hosts are updated but there is no other changes that trigger target pool update (for which we delete&recreate target pool and hence updates the hosts). So the main change here is detecting that condition and call `updateTargetPool()`.

PSP: improve parsing and validation of SELinux levels
**What this PR does / why we need it**:
At this moment, when we're comparing SELinux levels of PSP and container, we compare them as strings. We don't take into account that categories in a level may be specified in a different order (for example, `s0:c0,c6` is the same as `s0:c6,c0`).
This PR improves handling of SELinux levels by doing logical comparison.

By default block service proxy to external IP addresses.
**What this PR does / why we need it**:
Currently, the Service Proxy on the APIServer allows unrestricted access to any IP address that the APIServer machine can reach. This is likely undesirable in many cases.
Update the service proxy so that it filters Endpoints to only those that have a TargetRef that matches a known Pod.
Fixes https://github.com/kubernetes/kubernetes/issues/58761
**Release note**:
```release-note
By default disable access to external IP addresses from the apiserver service proxy.

Add a container type to the runtime manager's container status
**What this PR does / why we need it**:

This feature gate was redundant with the `--config` flag, which already
enables/disables loading Kubelet config from a file.
Since the gate guarded an alpha feature, removing it is not a violation
of our API guidelines.
Some stuff in `kubernetes/test-infra` currently sets the gate,
so removing will be a 3 step process:
1. This PR, which makes the gate a no-op.
2. Stop setting the gate in `kubernetes/test-infra`.
3. Completely remove the gate.

Fix master regex when running multiple clusters
**What this PR does / why we need it**:
I'm running two Kubernetes clusters on GCE. One for production and one for staging. The instance prefix I use for production is `kubernetes` and for staging it's `staging-kubernetes`. This caused a problem when running `kube-up.sh` for production because when it tries to find all instances which match `kubernetes(-...)?` it finds both the production and staging instances. This probably results in multiple problems, but the most noticeable one for me was that `INITIAL_ETCD_CLUSTER` was incorrect and so etcd wouldn't start up correctly so the api server doesn't start up correctly so nothing else starts up. I tested this manually and it seems to work for me, but I didn't write an automated test.
