      commitQuorum is accepted without error on 4.2 servers despite not having any effect on createIndexes (it does have an effect starting in 4.3/4.4). All other invalid options passed to createIndexes do return errors, and the drivers rely on this to communicate errors to end users. Since commitQuorum doesn't have an effect on 4.2, it should throw an error as if it's invalid too.
