[rdo-dev] Regenerate secrets required by zuul jobs

Greetings, With recent Jenkins security advisory today, I realized we just imported the current secrets from jenkins into zuulv3. I'd like to propose, just to be extra safe, we preform a re-key of everything that uses secrets. I'm not sure if this has every been done with jenkins, but we should also consider some policy to re-key everything ever x months too. Thoughts?
