Use Prometheus instrumentation conventions
The `System` and `Subsystem` parameters are subject to removal.
(x-ref: https://github.com/prometheus/client_golang/issues/240)
All metrics should use base units, which is seconds in the duration
case.
Counters should always end in `_total` and metrics should avoid
referring to potential label dimensions. Those should rather be
mentioned in the documentation string.
@kubernetes/sig-instrumentation
Reference docs:
https://prometheus.io/docs/practices/instrumentation/https://prometheus.io/docs/practices/naming/
**Release note**:
```
Breaking change: Renamed REST client Prometheus metrics to follow the instrumentation conventions ("request_latency_microseconds" -> "rest_client_request_latency_seconds", "request_status_codes" -> "rest_client_requests_total"). Please update your alerting pipeline if you rely on them.

e2e test: Log container output on TestContainerOutput error
When a pod started with TestContainerOutput or TestContainerOutputRegexp
fails from unknown reason, we should log all output of all its containers
so we can analyze what went wrong.
This would help us to see what wrong in https://github.com/kubernetes/kubernetes/issues/40811 - a container is running there for 3 minutes and dies and we want to see what it did for these 3 minutes.

Change the junit file name format to `junit_image-name_id.xml`,
With this, the junit file name will be `junit_image-name_id.xml:
```
junit_containervm_id.xml
junit_coreos-alpha_id.xml
junit_gci_id.xml
junit_ubuntu-docker10_id.xml
junit_ubuntu-docker12_id.xml
```
The test infra team will use the `image-name` inside the junit file name and replace the original `[1] [2] [3] ..` with the actual image name.
This will make it a little bit easier for debugging.

Remove VCenterPort from vsphere cloud provider.
**What this PR does / why we need it**:
Address a bug inside vsphere cloud provider when a port number other than 443 is specified inside the config file.
The url which is used for communicating with govmomi should not include port number.
A port number other than 443 will result in 404 error.
VCenterPort stays in VSphereConfig structure for backward compatibility.

Node version cannot be higher than the master version, so we must

Create DefaultPodDeletionTimeout for e2e tests
In our e2e and e2e_node tests, we had a number of different timeouts for deletion.
Recent changes to the way deletion works (#41644, #41456) have resulted in some timeouts in e2e tests. #42661 was the most recent fix for this.
Most of these tests are not meant to test pod deletion latency, but rather just to clean up pods after a test is finished.
For this reason, we should change all these tests to use a standard, fairly high timeout for deletion.

Don't wait for the final deletion of pod
The final deletion of the pod depends on kubelet and other components operating correctly. The purpose of this e2e test is verifying the clientset can handle deleteOptions correctly, so waiting for the deletionTimestamp and deletionGraceperiod get set is good enough.
In the long run, we should move this set of e2e tests to integration tests.

add debugging to the client watch test
Adds debugging information for https://github.com/kubernetes/kubernetes/issues/42724. I suspect that the watch is closing early, but I'd like proof before I consider things like retrying the list and doing another watch to observe the delete. I'm not even sure that would satisfy the test
It seems like a flaky way to build the test. Why wouldn't we delete non-gracefully?

Fixed potential OutOfSync of nodeInfo.
The cloned NodeInfo still share the same resource objects in cache; it may make `requestedResource` and Pods OutOfSync, for example, if the pod was deleted, the `requestedResource` is updated by Pods are not in cloned info. Found this when investigating #32531 , but seems not the root cause, as nodeInfo are readonly in predicts & priorities.
Sample codes for `&(*)`:
```
package main
import (
"fmt"
)
type Resource struct {
A int
}
type Node struct {
Res *Resource
}
func main() {
r1 := &Resource { A:10 }
n1 := &Node{Res: r1}
r2 := &(*n1.Res)
r2.A = 11
fmt.Printf("%t, %d %d\n", r1==r2, r1, r2)
}
```
Output:
```
true, &{11} &{11}
```
