Unify fluentd-gcp configurations
There're two different configs and two different pod specs for fluentd agent for GCL: one for GCI and one for CVM. This PR makes it possible to use only one config and only one pod spec.

Don't update gcloud in cluster/*/util.sh
**What this PR does / why we need it**:
Removes automatic gcloud update commands from `cluster/gce/util.sh`, `cluster/gke/util.sh`. Setting env `KUBE_PROMPT_FOR_UPDATE=y` will update required components, otherwise it will only verify that required components are present and at a minimum required version.
**Which issue this PR fixes** *(optional, in `fixes #<issue number>(, #<issue_number>, ...)` format, will close that issue when PR gets merged)*: fixes#35834
**Special notes for your reviewer**:
Inline python is nasty but I *really* don't want to do version comparison in bash. Open to other suggestions for verifying required version of gcloud components. cc @kubernetes/sig-cluster-lifecycle, @kubernetes/sig-testing

Set strategy spec for kube-dns to support zero downtime rolling update
From #37728 and coreos/kube-aws#111.
Set `maxUnavailable` to 0 to prevent DNS service outage during update when the replica number is only 1.
Also keeps all kube-dns yaml files in sync.

Collect logs for dead kubelets too
Collect logs via journalctl if journalctl is installed, rather than only if
kubelet.service is running. The old way resulted in us losing logs any
time the kubelet was failing. This, of course, breaks on a node if
someone decided to install journalctl but not use it. But that is not
the case on any of the images used by cluster-level tests at present.
^^^^FYI @Random-Liu not sure if `which journalctl` implies that journalctl is actually used on all of the nodes we test in the node-e2e suites. This may be of consequence if we move to using `cluster/log-dump.sh` to scrape logs for node-e2e.
P0 because this is somewhat in the way of debugging https://github.com/kubernetes/kubernetes/issues/33882
@jessfraz @saad-ali This should be cherry-picked to 1.4 and 1.5 as well.

log-dump: Change USE_KUBECTL path to instead call out to a custom function
**What this PR does / why we need it**: 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 ...

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.

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.

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-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`.
