Refactor lookup init and add routing table metric

I think it would be nice to see the detailed routing table occupancy.
I've added a metric that exposes the current occupancy of each bucket.
That should provide me some insight into the current distribution of
nodes and if we need to find a way to keep the closer buckets alive.
