there is an issue with butler where if you have to manager sections (eg: prometheus, alertmanager), and butler will create prometheus metrics for both of those.
If you remove the configuration for one of the managers, then the prometheus metrics will still hang about, and that's bad.
@kirharri suggests that at each config retrieval iteration, then blow away all the metrics, and re-write them.
