Fixes link to point to CRI-O sock constant defined in cadvisor. We
cannot pin directly because of linux build tags in transitive dependency
opencontaines/runc.

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.
* Add a new package under nodeshutdown "systemd"
* Package uses dbus to interface with logind to manage shutdown
inhibitors
* Make github.com/godbus/dbus a new explicit dependency
* Update vendor and go modules
Pod object is more flexible to use and construct
* Update TestGetTopologyHints() to work according to new test cases
* Update topologyHintTestCase{} to include proper field

* Extract common tests cases that will be used for both GetTopologyHints()
and GetPodTopologyHints()
* Extract machineInfo as it will be used for both functions as well

* Add topologyScopeName parameter to NewManager().
* Add scope interface and structure that implement common logic
* Add pod scope & container scopes
* Add pod lifecycle functions

This PR changes the buckets of the
kubelet_runtime_operation_duration_seconds metric to be
metrics.ExponentialBuckets(.005, 2.5, 14) in order to
allow debugging image pull times. Right now the biggest bucket is 10
seconds, which is an ordinary time frame to pull an image, making the
metric useless for the aforementioned usecase.
It covers deviceplugin & cpumanager.
It has drawback, since cpuset and all other structs including cadvisor's keep
cpu as int, but for protobuf based interface is better to have fixed
int.
This patch also introduces additional interface CPUsProvider, while
DeviceProvider might have been extended too.
Checkpoint not covered by unit test.
