Sometimes an informer might not directly send the deleted object to the
OnDelete callback, but rather a DeletedFinalStateUnknown. The AssumeCache did
not handle that case.

The means by which we extract and parse the version of an API object is
not specific to etcd3. In order to allow for a generic suite of tests
against any storage.Interface imlpementation, we need this logic to live
outside of the etcd3 package, or import cycles will exist.

This patch aims to simplify decoupling "pkg/scheduler/framework/plugins"
from internal "k8s.io/kubernetes" packages. More described in
issue #89930 and PR #102953.
Some helpers from "k8s.io/kubernetes/pkg/controller/volume/persistentvolume"
package moved to "k8s.io/component-helpers/storage/volume" package:
- IsDelayBindingMode
- GetBindVolumeToClaim
- IsVolumeBoundToClaim
- FindMatchingVolume
- CheckVolumeModeMismatches
- CheckAccessModes
- GetVolumeNodeAffinity
Also "CheckNodeAffinity" from "k8s.io/kubernetes/pkg/volume/util"
package moved to "k8s.io/component-helpers/storage/volume" package
to prevent diamond dependency conflict.

The feature gate gets locked to "true", with the goal to remove it in two
releases.
All code now can assume that the feature is enabled. Tests for "feature
disabled" are no longer needed and get removed.
Some code wasn't using the new helper functions yet. That gets changed while
touching those lines.
The name concatenation and ownership check were originally considered small
enough to not warrant dedicated functions, but the intent of the code is more
readable with them.
UnschedulableAndUnresolvable
This change adds an additional check in the volumebinding scheduler
plugin to handle PVC with phase ClaimLost which will allow the
scheduler to return UnschedulableAndUnresolvable during the PreFilter
stage and skip the rest of the node evaluation since the PVC is
bound to a PV that does not exist.
Without this change, the FailedScheduling error message would look like:
0/10 nodes are available: 2 node(s) had taint {node/test: true},
that the pod didn't tolerate, 6 node(s) had taint {node/unhealthy: true},
that the pod didn't tolerate, 2 pvc(s) bound to non-existent pv(s)
Which is still evaluating every single node to determine that the pod
cannot be scheduled because the PVC is bound to a non-existent PV
With this change, the FailedScheduling error message would look like:
0/10 nodes are available: 1 persistentvolumeclaim "foo" bound
to non-existent persistentvolume "bar"

This change will make the message more clear when there
is a case of PVC(s) bound to PV(s) that no longer exists
and scheduler does not select the node due to this issue.
Previous error message would look like:
0/2 nodes are available: 2 pvc(s) bound to non-existent pv(s)
Updated message looks like:
0/2 nodes are available: 2 node(s) unavailable due to one or more
pvc(s) bound to non-existent pv(s)
For larger clusters with many different reasons of nodes that
are not available, the current message can be very misleading for
users to think that there are many PVCs lost due to PVs deleted but
in fact it could be just a single PVC case but many nodes not selected
by the scheduler due to this case.
