Make get-kube.sh smarter when choosing if it should download
The #19404 fix for #15197 doesn't work very well when this script is used in CI
Since our kubernetes release tarballs are always named `kubernetes.tar.gz`, checking timestamps alone won't guarantee we do the right thing. If we're trying to extract a different release than the version currently downloaded, both `curl` and `wget` will just use the preexisting version.
My change makes the caching a bit more explicit; we look inside the kubernetes tarball for the `version` file and compare that to the release requested.
I've also added some code to automatically delete the preexisting `kubernetes/` directory so that we don't get into a weird state with multiple versions extracted into the same root.
This is a lot of shell, and I've tested the various branches manually, but we definitely need a better way to automate testing this (or simplify/remove some of the functionality).

e2e node plumbing and bundling for GCI mounter
**Note:** The code in this PR only bundles the mounter and modifies `--mounter-path` if it can find `cluster/gce/gci/mounter` in the K8s source dir when building the test bundle.
This bundles the mounter script for GCI with the node e2e tests and allows the `--mounter-path` to be passed to the Kubelet via the node test framework. The node test runner will detect when we are running on a remote GCI node and add the appropriate `--mounter-path` to the `testArgs`.
It also includes a simple node test that mounts a tmpfs volume. This will exercise the Kubelet's mounter code path.
**ITEM OF NOTE:** To get the k8s root dir (in order to copy the mount script into the tarball), I changed `getK8sRootDir` -> `GetK8sRootDir` in `test/e2e_node/build/build.go`. Based on the comment above that function (and the fact that it was private to begin with), I'm not sure this is the best way to do things:
```
// TODO: Dedup / merge this with comparable utilities in e2e/util.go
```
On the other hand, the `e2e/util.go` file mentioned in that comment doesn't exist anymore. This should be resolved before this PR is merged.

**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)

Added option to specify the flannel backend, to cluster/ubuntu
```release-note
```
Generalized the cluster/ubuntu scripting so that there is a way to
specify the Flannel "backend" to use.
Also updated the default setting of ADMISSION_CONTROL, to match that
recommended for the latest release in
http://kubernetes.io/docs/admin/admission-controllers/#is-there-a-recommended-set-of-plug-ins-to-use,
and updated the comment on that setting to explain it.
Also made `cluster/ubuntu/reconfDocker.sh` sensitive to the `DEBUG` envar.
