This task is done when a new requirements.txt is merged into ores-wikimedia-config that includes all dependencies (recursively expanded) and exact version numbers.
To make sure that it is fully reproducible, this should be the output of pip freeze. This will:
- Recursively list all the exact versions of the modules we need
- Make it easier to process / do wheels for them all (See https://phabricator.wikimedia.org/T128110#2082243)
