Feature Request: Instructions for moving to production when using the template

[dwindibank]

@OmeGak, this template looks very useful.

One feature request: Can you provide the recommended way to move to production when using the template? (this could be a wiki page).

The vanilla setup for Indico development verse production is pretty different. We've hit issues on things like figuring out how to include our custom plugin JS and CSS if the make / webpack steps are not being run in production. Instructions on how to move to production using the template would be very helpful.

At least on the Indico upstream side, the recommended way to do any production deployment based on custom code is to build a Python wheel for Indico and any plugins that may be needed, and then installing those on the production system.

@OmeGak Maybe it would be a good idea for this template to include a GitHub actions job that builds such wheels? Feel free to re-use the one I use in the main Indico repo to build the wheels there.
