Priority is normally set by the admission controller when missing.
For static pods there seems to be some corner cases, as, if priority
is not explicitly set, Graceful Node Shutdown will shutdown
static pods with the other pods that have priority 0 or unset.

These testcases are too vague, they are not test against the scenario
they want, but instead all of them are failed due to client cannot
be created.
`kubeconfig` file is created and mocked the function of `loadConfig` in
order to make those testcases valid.

Dependencies need to be updated to use
github.com/container-orchestrated-devices/container-device-interface.
It's not decided yet whether we will implement Topology support
for DRA or not. Not having any toppology-related code
will help to avoid wrong impression that DRA is used as a hint
provider for the Topology Manager.
The controller uses the exact same logic as the generic ephemeral inline volume
controller, just for inline ResourceClaimTemplate -> ResourceClaim.
In addition, it supports removal of pods from the ReservedFor field when those
pods are known to not need the claim anymore. At the moment, only this special
case is supported. Removal of arbitrary objects would imply granting full read
access to all types to determine whether a) an object is gone and b) if the
current incarnation is the one which is listed in ReservedFor. This may get
added later.
This adds a new resource.k8s.io API group with v1alpha1 as version. It contains
four new types: resource.ResourceClaim, resource.ResourceClass, resource.ResourceClaimTemplate, and
resource.PodScheduling.
This change enables hot reload of encryption config file when api server
flag --encryption-provider-config-automatic-reload is set to true. This
allows the user to change the encryption config file without restarting
kube-apiserver. The change is detected by polling the file and is done
by using fsnotify watcher. When file is updated it's process to generate
new set of transformers and close the old ones.

This change adds a flag --encryption-provider-config-automatic-reload
which will be used to drive automatic reloading of the encryption
config at runtime. While this flag is set to true, or when KMS v2
plugins are used without KMS v1 plugins, the /healthz endpoints
associated with said plugins are collapsed into a single endpoint at
/healthz/kms-providers - in this state, it is not possible to
configure exclusions for specific KMS providers while including the
remaining ones - ex: using /readyz?exclude=kms-provider-1 to exclude
a particular KMS is not possible. This single healthz check handles
checking all configured KMS providers. When reloading is enabled
but no KMS providers are configured, it is a no-op.
k8s.io/apiserver does not support dynamic addition and removal of
healthz checks at runtime. Reloading will instead have a single
static healthz check and swap the underlying implementation at
runtime when a config change occurs.

This patch adds new Kubelet option topologyManagerPolicyOptions.
To introduce new TopologyManager options, first we need to introduce new
flag called `topology-manager-policy-options` to allow users to modify
behaviour of best-effort and restricted policies.

CPUManager is going GA, thus it makes little sense

With graduation of device plugins to GA in 1.26, the feature gate is
enabled by default so `devicePluginEnabled` field no longer needs to
be passed at the time of Container Manager creation.
In addition to that, we remove the `ManagerStub` as it is no longer
needed.

For parity with `init` and `join`, the test file only
covers some basic scenarios and is expected to be expanded
when the config file for `kubeadm reset` is ready.

The init config file fetched from cluster won't have `ignorePreflightErrors`
set, and shouldn't try to reuse it even it's set with any value.
Instead, it should be defined in reset config file and fetch from it when the
reset config is ready.

Currently, there are some unit tests that are failing on Windows due to
various reasons:
- config options not supported on Windows.
- files not closed, which means that they cannot be removed / renamed.
- paths not properly joined (filepath.Join should be used).
- time.Now() is not as precise on Windows, which means that 2
consecutive calls may return the same timestamp.
- different error messages on Windows.
- files have \r\n line endings on Windows.
- /tmp directory being used, which might not exist on Windows. Instead,
the OS-specific Temp directory should be used.
- the default value for Kubelet's EvictionHard field was containing
OS-specific fields. This is now moved, the field is now set during
Kubelet's initialization, after the config file is read.
Kube/proxy, in NodeCIDR local detector mode, uses the node.Spec.PodCIDRs
field to build the Services iptables rules.
The Node object depends on the kubelet, but if kube-proxy runs as a
static pods or as a standalone binary, it is not possible to guarantee
that the values obtained at bootsrap are valid, causing traffic outages.
Kube-proxy has to react on node changes to avoid this problems, it
simply restarts if detect that the node PodCIDRs have changed.
In case that the Node has been deleted, kube-proxy will only log an
error and keep working, since it may break graceful shutdowns of the
node.
Some of the unit tests cannot pass on Windows due to various reasons:
- fsnotify does not have a Windows implementation.
- Proxy Mode IPVS not supported on Windows.
- Seccomp not supported on Windows.
- VolumeMode=Block is not supported on Windows.
- iSCSI volumes are mounted differently on Windows, and iscsiadm is a
Linux utility.
- All certs will be created under the folder of `/etc/kubernetes/tmp/kubeadm-join-dryrunxxx`
if the `dry-run` mode is enabled.
- Try to make each phase idempotent by resetting the cert dir with `dry-run` mode

The phase `kubeadm init phase upload-certs` intends to be used if
secret "kubeadm-certs" is expired and deleted.
But the help msg was saying this command cannot run on its own.
It's fine to run this command on its own to upload local certs to secret.
