Use the luigi-own configuration

[nils-braun]

Instead of relying on our own settings implementation, we can also leverage the luigi configuration

This has my upvote, I would much prefer using the toml supported by luigi over json, especially for the ability to add comments to settings, as long as per default the old json format would still work.

Is your idea to add an additional way to read in settings via the luigi.cfg (or luigi.toml) file or a total reimplementation of the settings handling? i think the former could easily be implemented like this.

Good question.
I think the long term goal we need to tackle at some point is to bring many of our developments to the upstream repository.
For that, I would like to get rid of our custom settings logic - but keep the interface for backwards compatibility.
But you both made a good point: using toml instead of json is already better
