When using the eviction API, if a pod already has
a non-zero DeletionTimestamp, we don't need to check
PDBs as it has already been marked for deletion.
Currently, if you have a PDB set, it is possible for
a pod stuck in pending state to be prevented from
deletion even though there are in fact enough healthy
replicas.
This commit allows pods in Pending state to be removed.
This commit also adds associated unit tests.
related-bug: #80389
This implementation allows Pod to request multiple hugepage resources
of different size and mount hugepage volumes using storage medium
HugePage-<size>, e.g.
spec:
containers:
resources:
requests:
hugepages-2Mi: 2Mi
hugepages-1Gi: 2Gi
volumeMounts:
- mountPath: /hugepages-2Mi
name: hugepage-2mi
- mountPath: /hugepages-1Gi
name: hugepage-1gi
...
volumes:
- name: hugepage-2mi
emptyDir:
medium: HugePages-2Mi
- name: hugepage-1gi
emptyDir:
medium: HugePages-1Gi
NOTE: This is an alpha feature.
Feature gate HugePageStorageMediumSize must be enabled for it to work.
This combines container names into a single list because separating them
into a long, variable length string isn't particularly useful in the
context of an streaming error message.
Such declarations will make using the package exported identifiers impossible after the declaration or create confusion when reading the code.

conflict.
Adding unit test verify that deleteValidation is retried.
adding e2e test verifying the webhook can intercept configmap and custom
resource deletion, and the existing object is sent via the
admissionreview.OldObject.
update the admission integration test to verify that the existing object
is passed to the deletion admission webhook as oldObject, in case of an
immediate deletion and in case of an update-on-delete.

Make scope.Kind of pod/attach, pod/exec, pod/portforward, node/proxy,
service/proxy to their respective subresource Kind, instead of the
parent Kind. The kind is used by the admission webhook controller to
determine how to convert the object.
Events have long shown the most data of the core objects in their output, but that data is of varying use
to a user. Following the principle that events are intended for the system to communicate information back
to the user, and that Message is the primary human readable field, this commit alters the default columns
to ensure event is shown with the most width.
1. Events are no longer sorted in the printer (this was a bug and was broken with paging and server side
rendering)
2. Only the last seen, type, reason, kind, and message fields are shown by default, which makes the
message prominent
3. Source, subobject, count, and first seen are only shown under `-o wide`
4. The duration fields were changed to be the more precise output introduced for job duration (2-3 sig figs)

update tests to be specific about the versions they are testing
When setting up tests, you want to rely on your own scheme. This eliminates coupling to floating versions which gives unnecessary flexibility in most cases and prevents testing all the versions you need.
@liggitt scrubs unnecessary deps.
