Description
The cutover to iterators in LUCENE-7407 caused ValueSourceAugmenter (which handles functions in the "fl" param along side other fields) resulted in FunctionValues being re-retrieved for every document.
Caching could cut that in half, but we should really retrieve a window at a time in order for best performance.
