Includes the following changes to profiler entries for queries:
-- The query field will contain find command parameters, e.g.
{find: <coll>, filter: {...}}.
-- Renames 'nscanned' to 'keysExamined' and 'nscannedObjects' to 'docsExamined'.
-- Renames 'scanAndOrder' to 'hasSortStage'.
-- Removes the top-level ntoreturn and ntoskip fields. Skip, limit, and
batchSize info will be present in the 'query' field instead.
