102124464a memory manager: improve the reserved memory validation logic 
We will have two layers of the validation.

- the first part of the validation logic will be implemented under the
`ValidateKubeletConfiguration` method
- the second one that requires knowledge about machine topology and
node allocatable resources will be implemented under the memory manager.

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.

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.

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
