LGTM

A word of warning though: counting rows this way is not cheap for big rocksdb tables and this will need to be rewritten at some point. For now it's fine and a good addition.

@dvdplm Yes, it is mainly added to debug the devnet. If we want to add this for long term, we may rely on some properties or another storage.
