Count the number of nodes and relationships on every db-meta update.

Display like we do in the viz legend.

Cool! Can we do that for all the labels + rel-types?
Either with: match (n:Label) return count(*) queries that should all execute in single ms.
Or with a trick in one query:

MATCH (:Label1) RETURN {label:'Label1', count:count(*)} as info
UNION ALL
MATCH (:Label2) RETURN {label:'Label2', count:count(*)} as info
UNION ALL
MATCH ()-[:TYPE1]->() RETURN {type:'TYPE1', count:count(*)} as info
