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.

705f97e171 Enable feature gate and kubelet flags for Topology Manager 
Nit: remove capitalization of preferred
Remove line from kubelet and add to separate PR for easier merge

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.
