Enable IPVS feature gateway by default since it's already beta
**What this PR does / why we need it**:
Per #60501, kubeadm init doesn't support the --feature-gates=SupportIPVSProxyMode=true flag anymore since IPVS is in beta and not alpha anymore. We should enable IPVS feature gateway by default to make kubeadm set up IPVS proxy properly.
**Which issue(s) this PR fixes**:
Fixes#60543
**Special notes for your reviewer**:
**Release note**:
```release-note
Enable IPVS feature gateway by default

dockershim: Return Labels as Info in ImageStatus.
c6ddc749e8 added an Info field to
ImageStatusResponse when Verbose is true. This makes the image's
Labels available in that field, rather than unconditionally returning
an empty map.
**What this PR does / why we need it**:
This PR exposes an image's `Labels` through the CRI. In particular, I want this so I can write an `ImageService` wrapper that delegates all operations to a real `ImageService` but also, when the right `Labels`, ensures any needed [nix store](https://nixos.org/nix/) paths are present on the system when an image is pulled, enabling users to use nix for package distribution while still using containers for isolation and kubernetes for orchestration. In general, though, this should be useful for anything that wants to know about an image's `Labels`
**Special notes for your reviewer**:
I'd prefer to put this change into the `Image` protobuf type instead of putting it into `Info` (gated by `Verbose` or not, available in other requests like `ListImages` or not), but that would be a change to the protocol and it seems `Info` was introduced exactly for this purpose. If it's acceptable to put this into `Image`, I'll rework this.
If this change is acceptable, I will also do the work for `cri-o`, `rktlet`, `frakti`, and `cri-containerd` where applicable.
I have started the process for my employer to sign on to the CLA. I don't have reason to expect it to take long, but because there is more work to do if this change is desired I'd prefer if we can start review before that is completed.
**Release note**:
```release-note
dockershim now makes an Image's Labels available in the Info field of ImageStatusResponse

Changing Flexvolume plugin directory on COS in GCE to a durable directory
**What this PR does / why we need it**: The original `/etc/srv/...` directory is in an overlayfs over a path in /tmp, so Flexvolume drivers are erased across node restarts for any reason. Changing it to non-tmpfs location.
Also removing redundant Flexvolume path injection in `config-test.sh` because it's already in `cluster/common.sh`.

Increase failureThresholds for failing HTTP liveness test
**What this PR does / why we need it**:
Removes test from e2e which relies on HTTP liveness as a measure to tell if the container is good or bad. While this is not a bad idea, we cannot rely on this test as HTTP liveness relies on network/infrastructure etc on which sometimes we have no control over. While increasing the timeout may be an option it may not be ideal for all cloud providers/type of hardware etc.

kube-scheduler: Support extender managed extended resources in kube-scheduler
**What this PR does / why we need it**:
This is the continuation of https://github.com/kubernetes/kubernetes/pull/58851.
- This PR adds new extender configurations in scheduler policy config.
- A set of extended resource names can be specified in an extender config. They are the resources that are managed by the extender. The scheduler will only send pods to the extender if the pod requests at least one of the extended resources in the set.
- An `IgnoredByScheduler` flag can be set along with each of such resources. If this flag is set to true, the scheduler will not check the resource in the `PodFitsResources` predicate.
- This PR also changes the default behavior of the `PodFitsResources` predicate. Now, by default, `PodFitsResources` will ignore the extended resources that are not in node status. This is required to support extender managed extended resources (including cluster-level resources) on node. Note that in kube-scheduler we override the default behavior by not ignoring such missing extended resources.

1. Raw records in ETCD that were processed by KMS Provider should be prefixed with k8s:enc:kms:v1:grpc-kms-provider-name:
2. Data Encryption Key (DEK) should be generated by envelopeTransformer and passed to KMS gRPC Plugin
3. KMS gRPC Plugin should encrypt the DEK with a Key Encryption Key (KEK) and pass it back to envelopeTransformer
4. The payload (ex. Secret) should be encrypted via AES CBC transform
5. Prefix-EncryptedDEK-EncryptedPayload structure should be deposited to ETCD

Add test/typecheck, a fast typecheck for all build platforms.
Add test/typecheck, a fast typecheck for all build platforms.
Most of the time spent compiling is spent optimizing and linking
binary code. Most errors occur at the syntax or semantic (type) layers.
Go's compiler is importable as a normal package, so we can do fast
syntax and type checking for the 10 platforms we build on.
This currently takes ~6 minutes of CPU time (parallelized).
This makes presubmit cross builds superfluous, since it should catch
most cross-build breaks (generally Unix and 64-bit assumptions).
Example output:
```$ time go run test/typecheck/main.go
