These three options are the ones from logs.AddFlags which are not deprecated.
Therefore it makes sense to make them available also via the configuration file
support in the one command which currently supports that (kubelet).
Long-term, all commands should use LoggingConfiguration, either with a
configuration file (as in kubelet) or via flags (kube-scheduler,
kube-apiserver, kube-controller-manager).
Short-term, both approaches have to be supported. As the majority of the
commands only use logs.AddFlags, that function by default continues to register
the flags and only leaves that to Options.AddFlags when explicitly requested.
A drive-by bug fix is done for log flushing: the periodic flushing called
klog.Flush and therefore missed explicit flushing of the newer logr
backend. This bug was never present in any release Kubernetes and therefore the
fix is not submitted in a separate PR.

This adds the gate `SeccompDefault` as new alpha feature. Seccomp path
and field fallbacks are now passed to the helper functions, whereas unit
tests covering those code paths have been added as well.
Beside enabling the feature gate, the feature has to be enabled by the
`SeccompDefault` kubelet configuration or its corresponding
`--seccomp-default` CLI flag.

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.
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.
When node lease feature is enabled, kubelet reports node status to api server
only if there is some change or it didn't report over last report interval.

Consolidate componentconfig code standards
**What this PR does / why we need it**:
This PR fixes a bunch of very small misalignments in ComponentConfig packages:
- Add sane comments to all functions/variables in componentconfig `register.go` files
- Make the `register.go` files of componentconfig pkgs follow the same pattern and not differ from each other like they do today.
- Register the `openapi-gen` tag in all `doc.go` files where the pkg contains _external_ types.
- Add the `groupName` tag where missing
- Fix cases where `addKnownTypes` was registered twice in the `SchemeBuilder`
- Add `Readme` and `OWNERS` files to `Godeps` directories if missing.
