Subject: [PATCH] feat: [AAP-59028] cleanup old redis artifacts

Also, we add a fail-fast task that makes impossible for a user to
silently run a misconfigured state thinking redis is backing EDA. We
then explicit to the user what needs to be changed. Documentation update
will be treated by a future change.
