Use GetByKey() in typeLister_NonNamespacedGet
The Get() function of non-namespace lister passes a temporary object to
indexer.Get() in order to fetch the actual object from the indexer. This
may cause Go to allocate the temporary object on the heap instead of the
stack, as it is passed into interfaces. For non-namespaced objects,
Get(&Type{ObjectMeta: v1.ObjectMeta{Name: name}}) should be equivalent
to GetByKey(name).
This could be the root cause of excessive allocations, e.g. in tests
clusterRoleLister.Get() has trigger 4 billion allocations. See
openshift/origin#16954

Fix dockershim panic when listing images

dockershim panic when listing containers because of `opts.Filters` not initialized:
505ccb88da/pkg/kubelet/dockershim/docker_image.go (L35-L39)
Also when imgSpec.Image is empty string, dockershim returns an empty image list which is not expected. (We should not set opts.Filters in this case).

Make AllocateResponse artifacts global across all devices per container in device plugin API
The current version of Device plugins returns artifacts (env vars, mounts, devices) per device, per container. This is not necessary and results in complex merging issues on kubelet side
There can still be a conflict if the artifacts returned by device plugin conflicts with the pod spec. In that case, I'd recommend failing pods in kubelet. This is yet to be addressed.
The go package name for device plugin apis is updated from `pkg/kubelet/apis/deviceplugin/v1alpha1` to `pkg/kubelet/apis/deviceplugin/v1alpha` (sub-version dropped) because we expect the alpha version to change until it graduates to beta and changing the go package everytime the actual alpha version changes is too tedious.
```release-note
Device plugin Alpha API no longer supports returning artifacts per device as part of AllocateResponse.
```
TODO:
- [x] Bump kubelet side API version
- [X] Post an updated device plugin image that works with the new API version
- [ ] Stabilize e2es (This PR needs to be merged since there is a dependency on the plugin side for vendoring)

Fixes spam from node status updates
Some of us are looking at reducing unncessary logging spam which happens in k8s. This message is anyway logged by caller of the function and hence we should not log it again.

Fixed the lease endpoint reconciler creation of kubernetes endpoint and lease file ttl. #53803
Fixed the prefix used to create the kubernetes endpoint and the ttl value used for lease files.
Fixes: #53803
There is no use case known for passing artifacts per device as it currently exists. The current API is also
complex to use for simple clients. Hence this PR creates a flat namespace where artifacts like environment variables
and mount points apply globally to all devices returned as part of AllocateResponse proto.

This updates the HPA controller to use the polymorphic scale client from
client-go. This should enable HPAs to work with arbitrary scalable
resources, instead of just those in the extensions API group (meaning we
can deprecate the copy of ReplicationController in extensions/v1beta1).
It also means that the HPA controller now pays attention to the
APIVersion field in `scaleTargetRef` (more specifically, the group part
of it).
Note that currently, discovery information on which resources are
available where is only fetched once (the first time that it's
requested). In the future, we may want a refreshing discovery REST
mapper.
Previously, we did not have custom code for fuzzing label selectors.
Anything that used a label selector (like Scale) had to manually bypass
fuzzing the selector, or write its own fuzzer. This introduces a fuzzer
for label selectors which generates random correct selectors with random
keys and values.
Previously, the fake RESTClient in client-go required a Registry. It
used the Registry to fetch the GroupVersion for the fake client.
However, the way it did so was dubious in some cases (it hard-coded the
default API group in places), and not strictly necssary.
This updates the fake client to just recieve the GroupVersion and
internal group name directly, instead of requiring a Registry, so that
it can be consumed in unit tests where a Registry isn't necessarily
readily available (e.g. elsewhere in client-go).

Added PreStopHooks to apiserver to allow clean shutdown.
BootStrapController now registers a PreStopHook to clean up the kubernetes service endpoints. The PreStopHooks allow the apiserver to shutdown cleanly under a controlled shutdown case. The BootStrapController's PreStopHook will clean up after itself by removing the apiserver from the list of IPs in the kubernetes service.
