It turns out that at some points while the Node is recovering from a
reboot, we get a different kind of error ("unable to upgrade
connection"). Since we can't distinguish these transient errors from an
error encountered after successfully executing the remote command,
let's just retry all errors for 5min. If this doesn't work, I'm gonna
blame it on sig-node.
The initial retry up to 20s was giving up too soon.
I'm seeing this test flake because the Node rebooted and it takes ~2min
to recover.
Now StatefulSet RunHostCmd calls will use the same 5min timeout as with
other Pod state checks.

AllowedNotReadyNodes allowed to be not ready for absolutely *any* reason
It's as good as we allow those many nodes to be not part of the cluster at all, ever.
Btw - currently our 5k-node correctness test fails if "kubelet stopped posting node status" or "route not created", etc (ref: https://storage.googleapis.com/kubernetes-jenkins/logs/ci-kubernetes-e2e-gce-scale-correctness/3/build-log.txt)
cc @kubernetes/sig-scalability-misc
We seem to get a lot of flakes due to "connection refused" while running
`kubectl exec`. I can't find any reason this would be caused by the test
flow, so I'm adding retries to see if that helps.

improve detectability of deleted pods
**What this PR does / why we need it**:
Adds comment to `waitForPodTerminatedInNamespace` to better explain how it's implemented.
~~It improves pod deletion detection in the e2e framework as follows:~~
~~1. the `waitForPodTerminatedInNamespace` func looks for pod.Status.Phase == _PodFailed_ or _PodSucceeded_ since both values imply that all containers have terminated.~~
~~2. the `waitForPodTerminatedInNamespace` func also ignores the pod's Reason if the passed-in `reason` parm is "". Reason is not really relevant to the pod being deleted or not, but if the caller passes a non-blank `reason` then it will be lower-cased, de-blanked and compared to the pod's Reason (also lower-cased and de-blanked). The idea is to make Reason checking more flexible and to prevent a pod from being considered running when all of its containers have terminated just because of a Reason mis-match.~~

Add node e2e tests for GKE environment
Ref: https://github.com/kubernetes/kubernetes/issues/46891
This PR adds node e2e tests for validating images used on GKE.
- We pass the `SYSTEM_SPEC_NAME` to the node e2e test process via the flag `--system-spec-name` so that we can skip the environment specific tests using `RunIfSystemSpecNameIs()`.
- Also added `SkipIfContainerRuntimeIs()` as the opposite of `RunIfContainerRuntimeIs()`.

Write reports for each upgrade test
Due to the way Ginkgo runs individual test cases and the level of coordination required for the upgrade tests, they were all run under a single Ginkgo test case. This PR generates and auxiliary report that break out the results of each upgrade test. This is accomplished by:
1) Wrapping `ginkgo.Fail` and `ginkgo.Skip` to get the actual failure or skip messages.
2) Recovering that info in the upgrade test to generate an auxiliary report.
I suggest reviewing commit by commit.

Make GCE load-balancers create health checks for nodes
From #14661. Proposal on kubernetes/community#552. Fixes#46313.
Bullet points:
- Create nodes health check and firewall (for health checking) for non-OnlyLocal service.
- Create local traffic health check and firewall (for health checking) for OnlyLocal service.
- Version skew:
- Don't create nodes health check if any nodes has version < 1.7.0.
- Don't backfill nodes health check on existing LBs unless users explicitly trigger it.
**Release note**:
```release-note
GCE Cloud Provider: New created LoadBalancer type Service now have health checks for nodes by default.
An existing LoadBalancer will have health check attached to it when:
- Change Service.Spec.Type from LoadBalancer to others and flip it back.
- Any effective change on Service.Spec.ExternalTrafficPolicy.

move from daemon_restart.go to framework/util.go
**What this PR does / why we need it**:
Moves the func `nodeExec` from daemon_restart.go to framework/util.go. This is the correct file for this func and is a more intuitive pkg for other callers to use. This is a small step of the larger effort of restructuring e2e tests to be more logically structured and easier for newcomers to understand.

Adding new tests to e2e/vsphere_volume_placement.go
**What this PR does / why we need it**:
Adding new tests to e2e/vsphere_volume_placement.go
Below is the tests description and test steps.
**Test Back-to-back pod creation/deletion with different volume sources on the same worker node**
1. Create volumes - vmdk2, vmdk1 is created in the test setup.
2. Create pod Spec - pod-SpecA with volume path of vmdk1 and NodeSelector set to label assigned to node1.
3. Create pod Spec - pod-SpecB with volume path of vmdk2 and NodeSelector set to label assigned to node1.
4. Create pod-A using pod-SpecA and wait for pod to become ready.
5. Create pod-B using pod-SpecB and wait for POD to become ready.
6. Verify volumes are attached to the node.
7. Create empty file on the volume to make sure volume is accessible. (Perform this step on pod-A and pod-B)
8. Verify file created in step 5 is present on the volume. (perform this step on pod-A and pod-B)
9. Delete pod-A and pod-B
10. Repeatedly (5 times) perform step 4 to 9 and verify associated volume's content is matching.
11. Wait for vmdk1 and vmdk2 to be detached from node.
12. Delete vmdk1 and vmdk2
**Test multiple volumes from different datastore within the same pod**
1. Create volumes - vmdk2 on non default shared datastore.
2. Create pod Spec with volume path of vmdk1 (vmdk1 is created in test setup on default datastore) and vmdk2.
3. Create pod using spec created in step-2 and wait for pod to become ready.
4. Verify both volumes are attached to the node on which pod are created. Write some data to make sure volume are accessible.
5. Delete pod.
6. Wait for vmdk1 and vmdk2 to be detached from node.
7. Create pod using spec created in step-2 and wait for pod to become ready.
8. Verify both volumes are attached to the node on which PODs are created. Verify volume contents are matching with the content written in step 4.
9. Delete POD.
10. Wait for vmdk1 and vmdk2 to be detached from node.
11. Delete vmdk1 and vmdk2
**Test multiple volumes from same datastore within the same pod**
1. Create volumes - vmdk2, vmdk1 is created in testsetup
2. Create pod Spec with volume path of vmdk1 (vmdk1 is created in test setup) and vmdk2.
3. Create pod using spec created in step-2 and wait for pod to become ready.
4. Verify both volumes are attached to the node on which pod are created. Write some data to make sure volume are accessible.
5. Delete pod.
6. Wait for vmdk1 and vmdk2 to be detached from node.
7. Create pod using spec created in step-2 and wait for pod to become ready.
8. Verify both volumes are attached to the node on which PODs are created. Verify volume contents are matching with the content written in step 4.
9. Delete POD.
10. Wait for vmdk1 and vmdk2 to be detached from node.
11. Delete vmdk1 and vmdk2
