I was surprise when I found out that `prefetch_related` calls are ignored
when using `Queryset.iterator`. I noticed in the docs here
https://docs.djangoproject.com/en/2.1/ref/models/querysets/#iterator that
it is because the "these two optimizations do not make sense together."
That may have been true in the past, but it is definitely not the case
now. The iterator allows chunking (by default 2000) and it would be very
helpful to prefetch related for each chunk.
