16f71c6d47 Implement shutdown manager in kubelet
Implements KEP 2000, Graceful Node Shutdown:
https://github.com/kubernetes/enhancements/tree/master/keps/sig-node/2000-graceful-node-shutdown

* Add new FeatureGate `GracefulNodeShutdown` to control
enabling/disabling the feature
* Add two new KubeletConfiguration options
  * `ShutdownGracePeriod` and `ShutdownGracePeriodCriticalPods`
* Add new package, `nodeshutdown` that implements the Node shutdown
manager
  * The node shutdown manager uses the systemd inhibit package, to
  create an system inhibitor, monitor for node shutdown events, and
  gracefully terminate pods upon a node shutdown.

a232971d73 Add public documentation for kubelet/apis/config
The `kubelet/apis/config` package had golint failures. This change-set
removes the `kubelet/apis/config` package from the `.golint_failures`
and fixes the golint errors. In particular, this change-set adds
documentation to the public types in the package.

This change-set works towards issue#68026

bba15d358c Add strict deserialization for kubelet component config
CodecFactory is started with EnableStrict that throws an error when deserializing
a Kubelet component config that is malformed (e.g. unknown or duplicate keys).

When strict decoding a v1beta1 config fails, non-strict decoding is used and a warning is emitted.
For this, NewSchemeAndCodecs is now a variadic function that can take multiple
arguments for augmenting the returned codec factory. Strict decoding is
then explicitely enabled when decoding a kubelet config.
Additionally, decoding a RemoteConfigSource needs to be non-strict
to avoid an accidental error when it contains newer API fields that are not
yet known to the Kubelet.

DecodeKubeletConfiguration returns a wrapped error instead of a simple string
so its type can be tested.

Add unit tests for unhappy paths when loading a component config

Add keys for test cases struct fields, remove nil field initialization

nit: dependency added to separate PR

Add check to ensure strict policy cannot be set without feature gate enabled

Topology Manager runs "none" policy by default.

Added constants for policies and updated documentation.
