Switch to use metrics/v2 everywhere in control&daemon code and in all the libraries they use. Don't have any internal magically create metrics, instead inject all metrics from the outside, so that the user of a library is in full control of what metrics get exposed. With the newly introduced option pattern for metrics it's also possible to select the registry as well as customizing the collector for certain metrics, this can for example be leveraged to only expose certain metrics on demand.
