This will deflake autoscaling e2e tests on gke. When there is already an operation running on the cluster, the node pool deletion will fail. This will in turn make other tests that add extra node pool fail.

Add e2e test for external metrics with Stackdriver
**What this PR does / why we need it**:
Adds e2e tests for external metrics using Stackdriver adapter.
Rename the file to note that these are Stackdriver tests in anticipation of tests running with fake custom metrics apiserver. Refactor the tests to be more structured.
**Release note**:
```
NONE

Add e2e test for custom metrics with Prometheus and Stackdriver
**What this PR does / why we need it**:
Add e2e test for custom metrics in a setup with a container exposing metrics in Prometheus format and prometheus-to-sd sidecar container scraping the metrics and writing them to Stackdriver.
Also some test refactoring for adding new tests more easily (plan to add scale down tests and a test with scaling on two metrics).

Regional support in Cluster Autoscaler e2e tests.
**What this PR does / why we need it**:
When calling GKE API and gcloud in Autoscaling e2 tests, take into account that clusters can be regional.
This currently uses MultiZonal as an indicator that cluster is regional, which is suboptimal, but considering that our tests do not work with multizonal clusters at the moment, there is no regression.This should be changed once there is an indicator available that the cluster is regional.
**Release note**:
```
NONE

Fix Incorrect Scale Subresources and HPA e2e ScaleTargetRefs
The HPA e2es failed to actually set `apiVersion` on the created HPAs, which previous was ignored. Since the polymorphic scale client was merged, this behavior is no longer tolerated (it was never correct to begin with, but it accidentally worked).
Additionally, the `apps` resources have their own version of scale. Until `apps/v1beta1` and `apps/v1beta2` go away, we need to support those versions in the scale client.
Together, these broke some of the HPA e2es.
Fixes#54574
```release-note
NONE
```
Previously, the HPA controller ignored APIVersion when resolving the
scale subresource for a kind, meaning if it was set incorrectly in the
HPA's scaleTargetRef, it would not matter. This was the case for
several of the HPA e2e tests.
Since the polymorphic scale client merged, APIVersion now matters. This
updates the HPA e2es to care about APIVersion, by passing kind as a full
GroupVersionKind, and not just a string.
