I'm not so sure about this anymore. Positional arguments would break a lot
in the design of the `ParameterUtil`.
For example the export to the web interface, the Configuration object or
Properties.

> Hadoop users are used to setting job configuration through "-D" on the
> command line.
> Right now, Flink users have to manually parse command line arguments and pass

> It would be nice to provide a standard args parser with is taking care of
> such stuff.
