> we leave an empty current-state and external-view when a resource has been
> dropped. for systems that frequently add/drop resources, this leave many
> empty znodes under current-state and external-view. we need:
> 1) fix this in helix
> 2) have a tool that auto clean current-state and external-view for dropped
> resources
