CRI: Add presubmit CRI validation test.
For #31459.
This PR adds a new suite for CRI presubmit validation which runs non-flaky, non-serial, non-slow test per-pr.
Except this PR, I'll also change the test-infra side. Ideally, after this is done, we should be be able to trigger CRI validation test per-pr with something like `@k8s-bot cri node e2e test this` and `@k8s-bot cri e2e test this`.

Add option to set a service nodeport
**Release note**:
```release-note
Add kubectl --node-port option for specifying the service nodeport
```
This patch adds the option to set a nodeport when creating a NodePort
service. In case of a port allocation error due to a specified port
being out of the valid range, the error now includes the valid
range. If a `--node-port` value is not specified, it defaults to zero, in
which case the allocator will default to its current behavior of
assigning an available port.
This patch also adds a new helper function in `cmd/util/helpers.go` to
retrieve `Int32` cobra flags.
**Example**
```
# create a nodeport service with an invalid port
$ kubectl create service nodeport mynodeport --tcp=8080:7777 --node-port=1
The Service "mynodeport" is invalid: spec.ports[0].nodePort: Invalid
value: 1: provided port is not in the valid range. Valid ports range
from 30000-32767
# create a nodeport service with a valid port
$ kubectl create service nodeport mynodeport --tcp=8080:7777 --node-port=30000
service "mynodeport" created
# create a nodeport service with a port already in use
$ kubectl create service nodeport mynodeport --tcp=8080:7777 --node-port=30000
The Service "mynodeport" is invalid: spec.ports[0].nodePort: Invalid value: 3000: provided port is already allocated
$ kubectl describe service mynodeport
Name: mynodeport

Labels: app=mynodeport

use service accounts as clients for controllers
Makes it possible for the controller-manager to use service accounts to run individual controllers. To start, this only enables this feature if this particular controller manager has the power to create service account tokens. Otherwise, the full-powered client is used instead. This is a necessary step on the way to subdividing the authority of controllers.

Allow empty annotation values
Related downstream issue: https://github.com/openshift/origin/issues/11175
**Release note**:
```release-note
release-note-none
```
Annotations with empty values can be used, for example, in diagnostics
logging. This patch removes the client-side check for empty values in
an annotation key-value pair.
**Before**
```
$ kubectl annotate pod zookeeper-1 node-selector="" --overwrite
error: invalid annotation format: node-selector=
```
**After**
```
$ kubectl annotate pod zookeeper-1 node-selector="" --overwrite
pod "zookeper-1" annotated
```
```
$ kubectl get po/zookeeper-1 --template='{{.metadata.annotations}}'
map[... node-selector: test-label:test]
```

Fix#31085, include output checking in retry loop
Fix#31085.
`wget -qO-` might omit the error and `RunHostCmd()` won't be able to catch it sometimes. Verify stdout is not empty within the retry loop to fix. Test passed 1500+ times in a row.

Fix call to Index call in listers
This will actually eliminated all logs like this:
```

```
And it should also speed up different things (as so far we we basically not using indexes at all.

Check for empty string post trimming
We curl in a retry loop and timeout, trimming stdout to find endpoint names. When curl hits the timeout, stdout is empty, so we insert the empty string into the received set of endpoints.
