When adding the ephemeral volume feature, the special case for
PersistentVolumeClaim volume sources in kubelet's host path and node
limits checks was overlooked. An ephemeral volume source is another
way of referencing a claim and has to be treated the same way.
* Use utilpointer to get a pointer
* Add tests for kubelet default configs
* Change copyright year from 2015 to 2021
* Run gofmt
* Add all negative and all positive test cases
The GetAllocatableDevices, needed to support the podresources
API, doesn't take into account the device health when computing
its output.
In this PR we address this gap and add unit tests along the way
to prevent regressions. This gives us a good initial coverage,
E2E tests to cover this case are much harder to write, because
we would need to inject faults to trigger the unhealthy status.
We will evaluate if adding these tests into later PRs.

Remove the VolumeSubpath feature gate.
Feature gate convention has been updated since this was introduced to
indicate that they "are intended to be deprecated and removed after a
feature becomes GA or is dropped.".
If a pod is killed (no longer wanted) and then a subsequent create/
add/update event is seen in the pod worker, assume that a pod UID
was reused (as it could be in static pods) and have the next
SyncKnownPods after the pod terminates remove the worker history so
that the config loop can restart the static pod, as well as return
to the caller the fact that this termination was not final.
The housekeeping loop then reconciles the desired state of the Kubelet
(pods in pod manager that are not in a terminal state, i.e. admitted
pods) with the pod worker by resubmitting those pods. This adds a
small amount of latency (2s) when a pod UID is reused and the pod
is terminated and restarted.
A pod that has been rejected by admission will have status manager
set the phase to Failed locally, which make take some time to
propagate to the apiserver. The rejected pod will be included in
admission until the apiserver propagates the change back, which
was an unintended regression when checking pod worker state as
authoritative.
A pod that is terminal in the API may still be consuming resources
on the system, so it should still be included in admission.
Prevent starting pods with resources satisfied by a single NUMA node on multiple NUMA nodes.
The code returned before it updated the minimal amount of NUMA nodes that can satisfy the container
requests.

The configuration is deprecated and targets removal for v1.23. Tests
cases have been changed as well.
