    Description

      We should validate the arguments sent to write concern so that if we add a field to write concern, old servers that don't support that field do not silently ignore it. Applications might assume they're getting durability guarantees they are not getting.
      Ex:

      > db.test.runCommand({insert : "test", documents : [], writeConcern : { foo : 1} } )
