Reconcile differences in production.j2 and production.example

[rmartz]

Overview

Over time, a small number changes have been made to either production.example but not production.j2 or vise versa. This confuses which one should be used, which is a significant impediment when creating a new instance or performing an instance upgrade.

This applies observed changes to the corresponding file, so the only differences should be differences of value.

Checklist

• PR has a descriptive enough title to be useful in changelogs

Testing Instructions

• Run

diff deployment/ansible/group_vars/production.{j2,example}

• The only differences should be variable value templating and {% raw %}/{% endraw %}

This seems like something that might fit in the ADVANCED section at the bottom, since it's just a reassignment of an already provided value that I suspect the user won't need to set themselves, like what we do with allowed_host:

DRIVER/deployment/ansible/group_vars/production.example

Lines 260 to 263 in 3ae5b47
