> Today we re-implement the same algorithm in various places
> when we want to consume all docs for a set/list of terms. This
> caused serious slowdowns for instance in the case of applying
> updates fixed in LUCENE-8602. This change extracts the common
> usage and shares the interation code including logic to reuse
> Terms and PostingsEnum instances as much as possble and adds
> tests for it.
