      When running a distinct query, the 'stats' still return using the keys from MongoDB 2.x:

      > mongo
MongoDB shell version: 3.0.0-rc8
connecting to: test
> db.runCommand({distinct: 'items', key: 'name', query: {offered: false}})
{
        "values" : [ ],
        "stats" : {
                "n" : 0,
                "nscanned" : 0,
                "nscannedObjects" : 0
        },
        "ok" : 1
}

      Since the explain output has renamed those stats keys' names, perhaps the distinct query should do the same for consistency. Specifically, those keys should be nReturned, totalKeysExamined, and totalDocsExamined. Best to do that before 3.0 goes gold, as it'll be more difficult and clumsy to perform later.
