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
to keep the names of the internal configuration
variables `Experimental*`.
Trivial rename only.

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.
