      Generate an internal SBE command for statistics analysis which runs the equivalent of 

       

       

      db.coll.aggregate( [
         { $project: {val : path} },
         { $_analyzeInternal: {} },
         { $merge: ... }
      ]);
      

       
      _analyzeInternal will be implemented in a follow-on ticket. For now it can simply consume values and emit an empty document at the end of the stream.

      The $merge is to replace (or insert) the value in the stats collection with the newly calculated value. Note that this requires a unique index on "path" which should be workable.
