Merge pull request #26027 from soltysh/scheduledjob_e2e
Automatic merge from submit-queue Scheduledjob e2e @erictune last element of the scheduledjob puzzle. I think we'll iterate on this once we have all the puzzles in place. This is one of those things that will be allowed to merge after code freeze. ```release-note * Introducing ScheduledJobs as described in [the proposal](https://github.com/kubernetes/kubernetes/blob/master/docs/proposals/scheduledjob.md) as part of `batch/v2alpha1` version (experimental feature). ``` []()
