YAML instead of JSON

[archenroot]

JSON is very verbose for config only, I suggest to move to YAML:

YAML is a superset of JSON - it only looks different.

Personally - after having spent days configuring Kubernetes deployments using YAML - I prefer JSON for basic config. Plus, I'd rather not have to introduce another dependency, if I don't have to (these can be problematic for some corporations that need to get approval for each and every package that they need to use).
