beorn7 f193f2b8ef Add a command to promtool that dumps metadata of heads.db ...

I needed this today for debugging. It can certainly be improved, but
it's already quite helpful.

I refactored the reading of heads.db files out of persistence, which
is an improvement, too.

I made minor changes to the cli package to allow outputting via the
io.Writer interface.
