The metrics daemon had counter classes that represented
persistent, tagged values, and UMA stats. To create some
derived UMA stats we need to separate persistency and UMA stats,
and the tagging doesn't help either.
This rewrite is supposed to keep the same functionality.

We want to be able to control the inclusion of the metrics_daemon,
which passively gathers power stats and the like and sends them
through the UMA pipeline iff the user has opted-in to metrics
collection.
