We've been having flakes with the TestDockercfgTokenDeletedController e2e test for a while. I've added enough debugging that it looks like the actual functionality is broken and only works ~70% of the time in the test. Someone needs to identify why dockercfg secret deletion is buggy (probably a data race) and fix it. The consequence here is that we may have invalid pull secrets being mounted into pods, especially during cert or token rotation. https://prow.svc.ci.openshift.org/view/gcs/origin-ci-test/logs/release-openshift-origin-installer-e2e-gcp-4.3/528
This test was not flaking before 10/24 - so something changed in master before that.
Per Clayton's comment, marking this as a release blocker.
