Enable basic auth username rotation for GCI
When changing basic auth creds, just delete the whole file, in order to be able to rotate username in addition to password.
Per Clayton's suggestion, move stuff from cluster/lib/util.sh to
hack/lib/util.sh. Also consolidate ensure-temp-dir and use the
hack/lib/util.sh implementation rather than cluster/common.sh.
If the file does not exist we will generate it as normal.
If the file exists we will remove the old admin password before adding
the "new" one. (Turns in to a no-op if the password exists).
This did not work properly before because we were replacing by key,
where the key was the password. New password would not match and so
not replace the old password.
Added a METADATA_CLOBBERS_CONFIG flag
METADATA_CLOBBERS_CONFIG controls if we consider the values on disk or in
metadata to be the canonical source of truth. Currently defaulting to
false for GCE and forcing to true for GKE.
Added handling for older forms of the basic_auth.csv file.
Fixed comment to reflect new METADATA_CLOBBERS_CONFIG var.

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

<!-- Steps to write your release note:

```release-note
`kube-up.sh`/`kube-down.sh` no longer force update gcloud for provider=gce|gke.

Make GKE detect-instance-groups work on Mac.
Make the fix from #27803 also work on mac.
The GNU `expr` command supports both the `expr match STRING REGEXP` and `expr STRING : REGEXP` command syntax.
The BSD `expr` command only has the `expr STRING : REGEXP` syntax.

Use --format='value(name)' with gcloud instead of grep/awk/cut
Fixing our fragile parsing of `gcloud` is getting old (#24746, #25159, maybe others?).
Instead, let's just get the proper output out of `gcloud` in the first place.

Fix GKE kube-up to correctly find an IGM from a multi-zone cluster
I've confirmed that this successfully brings up a cluster, fixing the immediate issue with the new e2e test. Sorry about not properly vetting it in the original PR (#24075).
This does cause a warning message to be printed based on the handling of the NUM_NODES variable though, which I could fix if you guys think it's worth it:
```
Detected 6 ready nodes, found 6 nodes out of expected 3. Found more nodes than expected, your cluster may not behave correctly.
```
