Fixes two issues with how the pod worker refactor calculated the
pods that admission could see (GetActivePods() and
filterOutTerminatedPods())
First, completed pods must be filtered from the "desired" state
for admission, which arguably should be happening earlier in
config. Exclude the two terminal pods states from GetActivePods()
Second, the previous check introduced with the pod worker lifecycle
ownership changes was subtly wrong for the admission use case.
Admission has to include pods that haven't yet hit the pod worker,
which CouldHaveRunningContainers was filtering out (because the
pod worker hasn't seen them). Introduce a weaker check -
IsPodKnownTerminated() - that returns true only if the pod is in
a known terminated state (no running containers AND known to pod
worker). This weaker check may only be called from components that
need admitted pods, not other kubelet subsystems.
This commit does not fix the long standing bug that force deleted
pods are omitted from admission checks, which must be fixed by
having GetActivePods() also include pods "still terminating".
This metrics is measured in seconds so it makes no sense starting from
1000 as init value. This breaks also the scheduler e2e metric thus make
users unable to compute, for example, their SLO for the scheduler.
Even if this metric is deprecated, it should behave correctly until it is
completely removed to avoid user confusion.
For example, for each volume created, the minimum value exposed
as a metric is 16.6min (1000sec/60) which is obviously wrong as logic.
In this commit, we migrate bucket creation to start from reasonable
numbers, copying the incrementation from the conventions that the
scheduler follows itself.

All dependencies of VolumeBinding plugin from
"k8s.io/kubernetes/pkg/controller/volume/scheduling" package moved to
"k8s.io/kubernetes/pkg/scheduler/framework/plugins/volumebinding" package:
- whole file pkg/controller/volume/scheduling/scheduler_assume_cache.go
- whole file pkg/controller/volume/scheduling/scheduler_assume_cache_test.go
- whole file pkg/controller/volume/scheduling/scheduler_binder.go
- whole file pkg/controller/volume/scheduling/scheduler_binder_fake.go
- whole file pkg/controller/volume/scheduling/scheduler_binder_test.go
Package "k8s.io/kubernetes/pkg/controller/volume/scheduling/metrics" moved
to "k8s.io/kubernetes/pkg/scheduler/framework/plugins/volumebinding/metrics"
because it only used in VolumeBinding plugin and (e2e) tests.
More described in issue #89930 and PR #102953.

When originally introduced, the field was made immutable to be
consistent with the other fields. But in practice allowing it to be
toggled makes more sense, in particular when considering the rollout
of a CSI driver (let it run without using the published
CSIStorageCapacity object, then flip the field, or upgrading from a
driver without support to one which supports it).
The only consumer of this field, the kube-scheduler, can handle
mutation without problems because it always consults the informer
cache to get the current value.
