      Description

      Get explain of find() to work through the legacy $explain at “queryPlanner” verbosity.

      Implementation strategy:
      • Expose a static method or function which takes a BSONObjBuilder and a pointer to a tree of stages. Should be able to convert this into the BSON for the queryPlanner section.
      • Leave existing explain implementation intact until it is truly dead code that can be deleted.
