Skip rather than fail networking tests on single node
**What this PR does / why we need it**:
Needed for the general e2e tidying we need to do for flakey slow tests, imo pre 1.5, see #31402 and so on.
**Which issue this PR fixes** *
Dont fail multinode tests if on a single node cluster, skip instead.

kubemark: add KUBEMARK_NUM_NODES and KUBEMARK_MASTER_SIZE config
A lot of test infra scripts are using these two parameters and repeatedly set NUM_NODES and MASTER_SIZE before running kubemark. When we try to use those scripts, we need to manually set these again and again.
It would come handy if kubemark config could take these into account and reduce duplication.

Fix nil pointer dereference in test framework
Checking the `result.Code` prior to `err` in the if statement causes a panic if result is `nil`. It turns out the formatting of the error is already in `IssueSSHCommandWithResult`, so removing redundant code is enough to fix the issue. Logging the SSH result was also redundant, so I removed that as well.

Node Conformance Test: Final cleanup for node conformance test.
This PR fits node conformance test with recent change.
* Remove `--manifest-path` because the test will get kubelet configuration through `/configz` now. https://github.com/kubernetes/kubernetes/pull/36919
* Add `$TEST_ARGS` so that we can override arguments inside the container.
* Fix a bug in garbage_collector_test.go which will cause the framework tries to connect docker no matter running the test or not. @dashpole
* Add `${REGISTRY}/node-test:${VERSION}` for convenience.
* Bump up the image version to `0.2`. (the one released with v1.4 is `v0.1`)
I've run the test both with `run_test.sh` script and directly `docker run`. Both of them passed.
After this gets merged, I'll build and push the new test image.

Per-container inode accounting test
Test spins up two pods: one pod uses all inodes, other pod acts normally. Test ensures correct pressure is encountered, inode-hog-pod is evicted, and the pod acting normally is not evicted. Test ensures conditions return to normal after the test.

Deploy a default StorageClass instance on AWS and GCE
This needs a newer kubectl in kube-addons-manager container. It's quite tricky to test as I cannot push new container image to gcr.io and I must copy the newer container manually.
cc @kubernetes/sig-storage
**Release note**:
```release-note
Kubernetes now installs a default StorageClass object when deployed on AWS, GCE and
OpenStack with kube-up.sh scripts. This StorageClass will automatically provision
a PeristentVolume in corresponding cloud for a PersistentVolumeClaim that cannot be
satisfied by any existing matching PersistentVolume in Kubernetes.
To override this default provisioning, administrators must manually delete this default StorageClass.

The LOG_DUMP_USE_KUBECTL path is fine, once the cluster is up.
However, we've had a continuous low-grade Up flake in the kops builds,
so I'd like to grab logs using the aws CLI.
This makes log-dump.sh extensible, so you can do:
function log_dump_custom_get_instances() { ... }
export -f log_dump_custom_get_instances
go run hack/e2e.go ...

Fixes dns autoscaling test flakes
Fixes #36457 and fixes#36569.
#36457 is flake due to the 10 minutes timeout for scaling down cluster. Changes to use `scaleDownTimeout` from [test/e2e/cluster_size_autoscaling.go](https://github.com/kubernetes/kubernetes/blob/master/test/e2e/cluster_size_autoscaling.go), which is 15 minutes.
The failure in #36569 is because we get the schedulable nodes number at the beginning of the test and assume it will not change unless we manually change the cluster size. But below logs indicate there may be nodes become ready after the test has begun.
```
[BeforeEach] [k8s.io] DNS horizontal autoscaling
/go/src/k8s.io/kubernetes/_output/dockerized/go/src/k8s.io/kubernetes/test/e2e/dns_autoscaling.go:71
Nov 10 00:36:26.951: INFO: Condition Ready of node jenkins-e2e-minion-group-x6w1 is false instead of true. Reason: KubeletNotReady, message: Kubenet does not have netConfig. This is most likely due to lack of PodCIDR
STEP: Replace the dns autoscaling parameters with testing parameters
Nov 10 00:36:26.961: INFO: DNS autoscaling ConfigMap updated.
STEP: Wait for kube-dns scaled to expected number
Nov 10 00:36:26.961: INFO: Waiting up to 5m0s for kube-dns reach 8 replicas
...
Expected error:
<*errors.errorString | 0xc420b17ef0>: {
s: "err waiting for DNS replicas to satisfy 8, got 9: timed out waiting for the condition",
}
err waiting for DNS replicas to satisfy 8, got 9: timed out waiting for the condition
not to have occurred
```
This fix puts the logic of counting schedulable nodes into the polling loop. By doing so, the test will have the correct expected replicas count even if schedulable nodes change in between.

Bumps up Addon Manager to v6.0 with full support of kubectl apply
Below images are built and pushed:
- gcr.io/google-containers/kube-addon-manager:v6.0
- gcr.io/google-containers/kube-addon-manager-amd64:v6.0
- gcr.io/google-containers/kube-addon-manager-arm:v6.0
- gcr.io/google-containers/kube-addon-manager-arm64:v6.0
- gcr.io/google-containers/kube-addon-manager-ppc64le:v6.0
The actual change made is upgrade kubectl version from `v1.5.0-alpha.1` to `v1.5.0-beta.1`, which is released today.
@mikedanese
@saad-ali This need to get into 1.5 because Addon Manager v6.0-alpha.1 (currently in used) does not have full support of `kubectl apply --prune`.

Fix concurrent read/write to map error in kubelet
Fix#37560.
The concurrent read/write is to the pod annotations. The call in apiserver.go reads the annotations, and the config.go writes the annotations. I moved the reads to config.go to avoid the race.

add wrapper to provide stderr on command errors
The go standard library doesn't include stderr in the error message, but in many cases it is present: https://golang.org/src/os/exec/exec.go#L389 . This adds a wrapper to display that information. I've added in it on spot where the kops test is having trouble. If it works well, we can add it elsewhere.

Fixing the logic to select first cluster in federated ingress controller
Ref https://github.com/kubernetes/kubernetes/issues/36074.
Before this change, ingress controller was using cluster with clusterIndex = 0 as the first cluster to create the ingress in.
But the ordering of clusters can change and hence ingress controller ended up creating the ingress in multiple clusters.
This PR fixes it by using an annotation on federated ingress. Controller now picks up a cluster randomly as the first cluster and creates ingress there. This clusters name is stored as an annotation on the federated ingress. Contoller does not create an ingress in any other cluster if this annotation is set on the federated ingress and IP has not been propagated. Once IP has been propagated, controller creates the ingress in all clusters.
