Fixes #256
Description
This adds a setting to enable caching query results when they're generators.
Rationale
Caching iterators causes OOM errors as documented in #256 when using
QuerySet.iteratorfor large result sets because of list coercion.I defaulted this setting to
Falsesince I think that's less surprising behavior, but this does change the existing behavior, so it would be a breaking change. Let me know if I should invert it to cache iterators by default as it currently does.
