Use federated namespace instead of the bootstrap cluster's namespace in Ingress e2e tests.
This should fix#31825.
cc @kubernetes/sig-cluster-federation @quinton-hoole
with StorageClass.Provisioner == <unknown plugin>, we should wait for
either external provisioner or volume admin to provide a PV for a claim
instead of reporting an error.
Fixes#31723

Remove net.ipv4.tcp_max_syn_backlog from sysctl whitelist
Remove `net.ipv4.tcp_max_syn_backlog` from sysctl whitelist. This is not namespaced in today's kernels, but must be set on node-level.
Having this on the whitelist, wouldn't harm because the kernel only offers namespaced `net.*` sysctls in the `/proc/sys` tree. But having a sysctl on the whitelist, which cannot be used, doesn't make sense either.
#### 1.4 justification:
- Risk: the whitelist is a published API. We shouldn't have sysctls on there which do not work.
- Rollback: nothing should depend on this behavior.
- Cost: the cost of this is relatively low, as no pod with this sysctl will launch.

Move StorageClass to a storage group
We discussed the pros and cons in sig-api-machinery yesterday. Choosing a particular group name means that clients (including our internal code) require less work and re-swizzling to handle promotions between versions. Even if you choose a group you end up not liking, the amount of work remains the same as the incubator work case: you move the affected kind, resource, and storage.
This moves the `StorageClass` type to the `storage.k8s.io` group (named for consistency with authentication, authorization, rbac, and imagepolicy). There are two commits, one for manaul changes and one for generated code.

Check for EmptyConfig errors when trying to use in-cluster config
By removing the default "localhost:8080" behavior several paths in
client config began returning err == ErrEmptyConfig rather than err ==
nil. The code checking for in cluster config was wrong - the logic
should be:
1. If loading the underlying config returns a non-empty error, fail
2. If the underlying config is not equal to the default config,
return that config (it has user input)
3. If it is possible to use in-cluster config, do so
4. Otherwise return the default config (and or default EmptyConfig
error).
Fixes#31910 @thockin @lavalamp @deads2k. We introduced EmptyConfig a very long time ago, but until I removed the "localhost:8080" Kubernetes was not actually exposing it (OpenShift relies on it since we don't set an insecure default). This properly falls through to in-cluster config in the described conditions.
```release-note
Some components like kube-dns and kube-proxy could fail to load the service account token when started within a pod. Properly handle empty configurations to try loading the service account config.

**What this PR does / why we need it**: When deleting deployments in the "overlapping deployment" e2e test, we check that the deployment's RSes & Pods are deleted as well. However, other RSes and Pods (that matches this deployment's selector) may be created by overlapping deployments right after this one is deleted. So when we check that, we should ignore those created by overlapping deployments.
**Which issue this PR fixes** *(optional, in `fixes #<issue number>(, #<issue_number>, ...)` format, will close that issue when PR gets merged)*: fixes#31502

Do not go into standalone mode when `--require-kubeconfig` is passed
**What this PR does / why we need it**:
We have change how missing `--api-servers` is treated with introduction of `--require-kubeconfig` (#30798), however we haven't introduced explicit `--standalone` flag for backwards-compatibility reasons. Right now, setting `--kubeconfig` and`--require-kubeconfig` still gets kubelet into standalone mode. In practice this means that it doesn't get to update `nodeInfo` and thereby may refuse to admit pods which had been assigned to it by the scheduler. For example, if you update labels for that given node, and try to use affinity or `NodeLabels` on a pod, it won't get to run.
**Which issue this PR fixes**: fixes#32085
**Special notes for your reviewer**: This fix is only until we introduce `--standalone` flag.

Set eviction-hard for vagrant cluster
In order to test eviction related functionality it will be convenient to have reasonable eviction defaults.
At this moment exactly same flags are used by GCE environment
kubelet will have a following flag:
--eviction-hard=memory.available<100Mi,nodefs.available<10%

fix log message to include ds name
The pod name is never set because newPod is created a couple lines up without a name. Instead log the name and namespace of the ds which the pod is created from.
also bump the log level because reasons loop get's hit fairly often and does not indicate a bug.

generated DeepCopy without a function on a struct pointer is wrong
in and out are both pointers to pointers, so *in has to be cast to
*Type, not Type.
@sttts hit this while debugging something else (most everything should be generated, but in this case the type is wrong)
