Automatic merge from submit-queue

Revert Revert of #28193

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 several concurrent GKE jobs.

This reverts commit ee1d4803.
