Since those are osm-internal objects it makes no sense to return them to timescaledb.

the drop_chunks api prints the names of the dropped chunks today.
I think we need to make the call on the OSM side whether these values should be printed or not when drop_chunks is invoked.
So far, we have been consistent with the behavior across APIs.
I don't want to change the hook definition in case we decide that drop_chunks should also behave consistently.
