Automatically download missing kube binaries in kube-up/kube-down.
**What this PR does / why we need it**: some users extract `kubernetes.tar.gz` and then immediately call `cluster/kube-up.sh` without first calling the new `cluster/get-kube-binaries.sh` script. As a result, the cluster fails to start, but it's not immediately clear why binaries are missing.
This PR streamlines this workflow by detecting this condition and prompting the user to download necessary binaries (using `cluster/get-kube-binaries.sh`).

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.

**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

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.

It seems like the `kubectl` behavior was introduced in #29236: if `current-context` is set to something invalid, it now complains.
This should avoid spamming build-log.txt with messages like:
perl: warning: Setting locale failed.

are supported and installed on your system.

OSX has shasum but not sha1sum, which is part of GNU coreutils.

**What this PR does / why we need it**:
Removes the deprecated configure-cbr0 flag and networking mode to avoid having untested and maybe unstable code in kubelet, see: #33789
**Which issue this PR fixes** *(optional, in `fixes #<issue number>(, #<issue_number>, ...)` format, will close that issue when PR gets merged)*:
fixes#30589fixes#31937
**Special notes for your reviewer**: There are a lot of deployments who rely on this networking mode. Not sure how we deal with that: force switch to kubenet or just delete the old deployment?
But please review the code changes first (the first commit)
