Enable ImageLocalityPriority by default with integration tests
**What this PR does / why we need it**:
This PR is a follow-up to [#63842](https://github.com/kubernetes/kubernetes/issues/63842). It moves the ImageLocalityPriority function to default priority functions of the default algorithm provider and adds integration tests for the updated scheduling policy.
- Compared to [#64662](https://github.com/kubernetes/kubernetes/pull/64662), this PR does note provide e2e test due to concerns about a large image may add too much overhead to the testing infrastructure and pipeline. We should add e2e tests in the future with the use of large enough image(s) in following PRs.
- Compared to [#64662](https://github.com/kubernetes/kubernetes/pull/64662), this PR simplifies the code changes and keeps code changes under test/integration/scheduler/.
- The PR contains a bug fix for [#65745](https://github.com/kubernetes/kubernetes/pull/65745) - caught by the integration test - where the image states are not properly cloned to the scheduler's cachedNodeInfoMap. We might split this fix into a separate PR.
The integration test covers what follows: a pod requiring a large image (~= 3GB) is submitted to the cluster and there is a single node in the cluster has the same large image; the pod should get scheduled to that node. We might also consider whether more scenarios are desired.

Retry scheduling on StorageClass events

Fixes#56163
**Special notes for your reviewer**:
I have taken over #60006.
It's hard to test in e2e, because we cannot know reschedule of pod is triggered by which event (periodically service/node events will move pods to active queue too). ~~I'll add integration tests for this functionality after [this PR](https://github.com/kubernetes/kubernetes/pull/65296) get merged.~~ (already added)
**Release note**:
```release-note
NONE
```
- Add resyncPeriod parameter for setupCluster to make resync period of
scheduler configurable.
- Add test case for static provisioning and delay binding storage class.
Move pods into active queue on PV add/update events.
- Add a stress test with scheduler resync to detect possible race
conditions.
This moves plugin/pkg/scheduler to pkg/scheduler and
plugin/cmd/kube-scheduler to cmd/kube-scheduler.
Bulk of the work was done with gomvpkg, except for kube-scheduler main
package.

Make scheduler integration test faster
Not to wait for 30 seconds for every negative test case. This commit
also organizes the test code to make it more readable.
It cuts the test time from 450s to 125s.
