The E2E test suite for rescheduling had a few bugs:

• Using the command line to stop a job with a failing deployment returns a non-zero exit code, which would cause an otherwise passing test to fail.
• Two of the input jobs were actually invalid but were only correctly detected as such because of core: fix kill_timeout validation when progress_deadline is 0 #17342

This changeset also updates the whole test suite to move it off the v1 "framework". The test assertions are otherwise left untouched.

Fixes: #19076
