we can't resolve this separately for 5.3 and 6.0. Making 6.0 fully
self-contained could mean that we end up having to maintain 3 separate copies
if we decide to go the same route for 5.3. Given
We either accept the cast or create a `elasticsearch-base-5.3` module that
both connectors depend on. It would be great for @tzulitai to weigh in here.
