debugdiscovery: display more statistic about the common set

We display a lot more information now. Especially, we display the overlap
between the common heads and the local/remote heads. There are various
optimization geared toward heads, as a result, the less common the heads the
more complex the discovery. Having this information easily accessible help when
working on discovery.
