…acts

The ci-kubernetes-e2e-kubeadm-gce test jobs are consistently failing. If you look at test results and logs for a given failing test job, and then compare it to the corresponding prior (prerequisite) bazel build job, you can see that the build job is pushing the build artifacts in the proper gs://kubernetes-release/bazel/... storage bucket, but the test job is extracting (or attempting to extract) build results from ci/latest. The test job also seems to be using inconsistent versions of kubeadm/kubelet/kubernetes.

This is very likely one of the causes of the CI test outages described in kubernetes/kubernetes#59762.

This failure mode is also seen in other ci-kubernetes-e2e-XXXX test cases, but I'd like to try a fix first on one representative test job, and then replicate the fix to other test jobs if it works.

Fixes kubernetes#6978
