      Adapt 3.15 "Evaluating $apply" accordingly.

      $apply on resource paths ending in /$count acts on the set "preceding" the /$count, the result is the plain-text number of items in the result of $apply, similar to the combination of /$count and $filter

      $count system query option is executed after $apply, @odata.count contains the number of items in the result of $apply

      Assume GET ~/Products/$count results in 100.
      Assume GET ~/Products?$apply=groupby((Name), aggregate(Sales/Amount with sum as Total)) results in a set with 4 entries (see example 50)

      What is the response for GET ~/Products/$count?$apply=groupby((Name), aggregate(Sales/Amount with sum as Total))?

      What is the value of @odata.count in the response for GET ~/Products?$apply=groupby((Name), aggregate(Sales/Amount with sum as Total))&$count=true?

      My proposal is: in both cases 4.
