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.

Since the filter status is missed for the phase of preemption, there
will be no way to tell why the preemption failed for some reasons, and
those reasons could be different with the status from the main scheduling
process (the first failed plugin will hide other failures in the chain).
This change provides verbose information based on the node status generated
during pod preemption, those information helps us to diagnose the issue which
is happened during pod preemption.

Refactor genericScheduler and signature of preemption funcs
- remove podNominator from genericScheduler
- simplify signature of preemption functions
Make Preempt() private
Previously, separate interfaces were defined for Reserve and Unreserve
plugins. However, in nearly all cases, a plugin that allocates a
resource using Reserve will likely want to register itself for Unreserve
as well in order to free the allocated resource at the end of a failed
scheduling/binding cycle. Having separate plugins for Reserve and
Unreserve also adds unnecessary config toil. To that end, this patch
aims to merge the two plugins into a single interface called a
ReservePlugin that requires implementing both the Reserve and Unreserve
methods.

Also adding result label to e2e_scheduling_duration_seconds. Previously, the metric was only updated for successful attempts
