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
```

Disable autoscaling before removing autoscaled node pool
This is to prevent flakes due to API calls failing in AfterEach during master restart, which is triggered by deleting an autoscaled node pool. Adding disable call before deleting node pool should prevent this as we'll wait for master restart in disableAutoscaler function.
While it may be faster to wait after deletion of autoscaled node pools, this is less complex and will be easier to remove in the future when changing autoscaling setttings no longer triggers master restart.

Fix failing autoscaling test in GKE
This should fix `[sig-autoscaling] Cluster size autoscaling [Slow] should increase cluster size if pending pods are small and there is another node pool that is not autoscaled [Feature:ClusterSizeAutoscalingScaleUp]` by getting a list of nodes from GKE nodepool in a different way (filtering nodes by labels.) Currently, gcloud command used for it is failing, as we only have GKE node pool name in the test and not the actual MIG name.
