kubeadm: Set the kubelet `--resolv-conf` flag conditionally on init
**What this PR does / why we need it**:
`kubeadm init` detects if systemd-resolved is running and configures the kubelet to use a working resolv.conf.
This patch also removes the warning message prompting manual user action for this configuration.

fix data loss issue if using existing azure disk with partitions in disk mount
**What this PR does / why we need it**:
When use an existing azure disk(also called [static provisioning](https://github.com/andyzhangx/demo/tree/master/linux/azuredisk#static-provisioning-for-azure-disk)) in pod, if that disk has multiple partitions, the disk will be formatted in the pod mounting.
This PR removes `formatIfNotFormatted` func in `WaitForAttach` which uses `lsblk` command to check whether disk is formatted or not
b87a392b1a/pkg/volume/azure_dd/azure_common_linux.go (L213-L215)
And finally the format disk operation will happen in `MountDevice` in which it uses common k8s code(`SafeFormatAndMount.GetDiskFormat`) using `blkid` to detect disk format, `blkid` could detect multiple partitions
b87a392b1a/pkg/util/mount/mount_linux.go (L541-L543)
- so if we use common k8s code(`SafeFormatAndMount.GetDiskFormat`), following error will be returned for mulitple partition disks, which is expected:

apiextensions: add ObjectMeta validation and pruning
This is a critical pre-requisite for further multi-version support and especially for GA of CRDs: ObjectMeta must be schema-validated and pruned, like `json.Unmarshal` does this.
This PR adds this in the incoming request serializer and the storage decoder. The former errors when schema validation fails, the later just drops invalid typed fields.
Fixes#59451
```release-note
Meta data of CustomResources is now pruned and schema checked during deserialization of requests and when read from etcd. In the former case, invalid meta data is rejected, in the later it is dropped from the CustomResource objects.

apimachinery: adapt ObjectConvertor invariant
We avoid deepcopies in the codec/conversion stack by re-using data structures. This means that the out object of a conversion must be deepcopied before mutation in order to not mutate the in object as well.
This guarantees that e.g. runtime.Encode (which uses conversion from internal -> versioned) does not mutate the input. This would be highly unexpected (and we do not mention possible mutation of the input for runtime.Encode).

remove extra "../" when copying from pod to local
**Release note**:
```release-note
NONE
```
Copying via `kubectl cp` from a pod to local will no longer panic if any received tar headers contain an extra "../". This can happen when specifying a remote location beyond "/" - for example:
```
# I am attempting to go backwards beyond "/"
$ kubectl cp mypod:/one/two/../../../etc/hosts ./
```
The above command results in a tar header containing an extra "../" in its name (../etc/hosts), causing a panic [here](https://github.com/kubernetes/kubernetes/blob/master/pkg/kubectl/cmd/cp.go#L388).

kubeadm: Refactor the Bootstrap Tokens usage in the API types
**What this PR does / why we need it**:
This PR:
- Moves some common, generic Bootstrap Token helpers and constants from `k8s.io/kubernetes/cmd/kubeadm/app/util/token` to `k8s.io/client-go/tools/bootstrap/token/`
- Breaks out the top-level Bootstrap Token fields to a dedicated `BootstrapToken` struct with helper functions.
- Instead of representing the Bootstrap Token as a plain `string`, there is now a wrapper struct `BootstrapTokenString` that can marshal/unmarshal correctly and supports validation on create, and splitting up the full token in the ID/Secret parts automatically.
- Makes kubeadm support multiple Bootstrap Tokens automatically by supporting a slice of `BootstrapToken` in the `MasterConfiguration` API object
- Consolidates the place for kubeadm to create token-related flags in an `options` package
- Supports automatic conversion from the `v1alpha1` to `v1alpha2` API
- Adds support to set token expiration directly instead of setting a TTL (Expiration and TTL are mutually exclusive)
- Removes the old `TokenDiscovery` struct we're not using anymore inside of kubeadm

I will also write unit tests tomorrow.
**Release note**:
```release-note
[action required] kubeadm: The Token-related fields in the `MasterConfiguration` object have now been refactored. Instead of the top-level `.Token`, `.TokenTTL`, `.TokenUsages`, `.TokenGroups` fields, there is now a `BootstrapTokens` slice of `BootstrapToken` objects that support the same features under the `.Token`, `.TTL`, `.Usages`, `.Groups` fields.

part of #59194
**Special notes for your reviewer**:
**Release note**:
```release-note
`ScheduleDaemonSetPods` is an alpha feature (since v1.11) that causes DaemonSet Pods
to be scheduler by default scheduler, instead of Daemonset controller. When it is enabled,
the `NodeAffinity` term (instead of `.spec.nodeName`) is added to the DaemonSet Pods;
this enables the default scheduler to bind the Pod to the target host. If node affinity
of DaemonSet Pod already exists, it will be replaced.
DaemonSet controller will only perform these operations when creating DaemonSet Pods;
and those operations will only modify the Pods of DaemonSet, no changes are made to the
`.spec.template` of DaemonSet.

Fix Windows CNI for the sandbox case
**What this PR does / why we need it**:
Windows supports both sandbox and non-sandbox cases. The non-sandbox
case is for Windows Server 2016 and for Windows Server version greater
than 1709 which use Hyper-V containers.
Currently, the CNI on Windows fetches the IP from the containers
within the pods regardless of the mode. This should be done only
in the non-sandbox mode where the IP of the actual container
will be different than the IP of the sandbox container.
In the case where the sandbox container is supported, all the containers
from the same pod will share the network details of the sandbox container.
This patch updates the CNI to fetch the IP from the sandbox container
when this mode is supported.
