[DO NOT MERGE] Temporary 3.7 deployment

[vitorguidi]

Motivation

We need the ability to maneuver code between 3.7 and 3.11 in order to rollback potential failure scenarios. This branch serves this purpose.

How to deploy:

outside of pipenv

PYTHON=python3.7 ./local/install_deps.sh python3.7 -m pipenv shell

within pipenv

regular butler command

Gotchas

Windows used to delete all of clusterfuzz files during update task, and this was resolved in #4025. This was added as the second commit in this PR

This, when deployed, will switch the k8s cronjobs to fetch the production code release and run python 3.7
