    Description

      Add ability to hint count commands.

      // using explicit command form
      db.runCommand({count:'test', query:{f:1}, hint:'_id_'})
       
      // using shell helper
      db.test.find({f:1}).hint('x_1').count()
      

      If there is no predicate for the query given to the count command, the hint will be ignored and the result will be pulled directly from the collection metadata.
