The runtime classes are apiserver's concept, while the handlers are kubelet's concept.
For NodeStatus, it makes more sense to return the latter ones here.

Kubelet, if using cloud provider external, initializes temporary
the node addresses using the non-cloud provider logic, until the
cloud provider overrides it.
This behavior has undesired consequences if the cloud-provider addresses
are different than the original ones, specially for hostNetwork pods,
that inherit these addresses from the Node.
Since some cloud-providers depend on this behavior, in order to keep
backward compatibility, assume that the specifying addresses via
the node-ip flags means that the intent is to keep the existing
behavior to temporary initialize the addresses.
If the node-ips are the unspecified addresses or are not set, then
wait for the external cloud provider to set the node addresses.

Though not obvious as currently written, PreferNodeIP() has different
semantics with legacy and external cloud providers, since one kind of
node IP value never gets passed in the external cloud provider case.
Split it into two functions to make this clearer (and to prepare for
adding new external-cloud-only semantics, and to make it clearer that
some of the code can be deleted when legacy cloud providers go away).
If you run "kubelet --cloud-provider X --node-ip Y", kubelet will set
an annotation on the node, but previously, if you then ran just
"kubelet --cloud-provider X" (or just "kubelet --node-ip Y"), it
wouldn't delete the stale annotation. Fix that.
This change is to promote local storage capacity isolation feature to GA
At the same time, to allow rootless system disable this feature due to
unable to get root fs, this change introduced a new kubelet config
"localStorageCapacityIsolation". By default it is set to true. For
rootless systems, they can set this configuration to false to disable
the feature. Once it is set, user cannot set ephemeral-storage
request/limit because capacity and allocatable will not be set.

When using a legacy cloud provider, if kubelet is passed a node address
in --node-ip it will use this address in preference out the the
addresses by the cloud provider.
When using an external cloud provider, kubelet will annotate the Node
with the first --node-ip for use by the cloud provider. The cloud
provider validates this annotation but does not otherwise use it,
meaning that --node-ip has no effect.
This change moves the node address filtering code from kubelet to
component-helpers and updates both kubelet and cloud-provider to use it.
There is no functional change to kubelet, but cloud-provider now honours
kubelet's --node-ip.
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.
Discussion is ongoing about how to best handle dual-stack with clouds
and autodetected IPs, but there is at least agreement that people on
bare metal ought to be able to specify two explicit IPs on dual-stack
hosts, so allow that.
* move well-known kubelet cloud provider annotations to k8s.io/cloud-provider
