Fix e2e testing logic

[upodroid]

I cleaned up some logic in the kubetest2-kops deployer. Some flags are automatically enabled when testing on GCE.

Got a successful test run by running the following config:

kubetest2 kops \
  -v 2 \
  --up --down \
  --cluster-name arm64.k8s.local \
  --cloud-provider=gce \
  --admin-access="0.0.0.0/0" \
  --gcp-project=borg-env \

@upodroid I added a question and some requests. I think this can be merged once all these are addressed.

[upodroid]

Can we merge this today please? I addressed what we discussed at the office hours

[upodroid]

The Google Service Account that prow runs with doesn't have permissions to make IAM changes on test projects. I can talk to @ameukam about it at a later date.
