Bring back #28193. We caught a break in
https://github.com/kubernetes/test-infra/issues/240 and discovered the
previous issue, fixed in
https://github.com/kubernetes/test-infra/pull/241 and
https://github.com/kubernetes/test-infra/pull/244, so I have a pretty
good handle on what was causing the previous bringup issues (and it
wasn't #28193). By the time this merges, we'll have good signal on GKE
in the `kubernetes-e2e-gke-updown` job.

This reverts commit ee1d4803.
