This POC is working with docker-compose, really cool to have HLS ! But I think we should rewrite the liquidsoap script before further additions

[jooola]

The HLS setup will add more coupling between nginx and playout, which isn't necessarily a problem, but might require more CLI knowledge for those who want to change some path configuration for example.

Maybe we should only install a hls setup behind a experimental feature flag until we iron out the way we want to install, manage it.

This will also allow us to experiment with HLS before having to expose it on the libretime interface.

[paddatrapper]

Hiding this behind a feature-flag is a good idea. Having some sort of feature-flag framework for experimental features in general may be something that we should look into
