reorder $limit before $lookup in pipeline

      In pipeline: 

      [ ... {$lookup:{}}, {$addFields:{}}, {$lookup:{}}, {$limit:10}, ... ]

      moving $limit before the first $lookup stage will significantly reduce the amount of work that lookup and addFields have to do. We currently don't reorder $limit with $lookup, it appears.
