    I like it. But I think it needs some functionality for verifying parameters. To let the
user specify some parameters that always need to be there and a description of the parameter.
Similar to how other tools print the "usage" when you don't give correct arguments.

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