Description

I think this is a blocker for LUCENE-6825, because the block KD-tree makes heavy use of OfflineSorter and we don't want to fill up tmp space ...

This should be a straightforward cutover, but there are some challenges, e.g. the test was failing because virus checker blocked deleting of files.
