------------------------------------------------------------
Actually I am thinking of making {{CliFrontend}} the unique CLI frontend. This
is based on the fact that we have a dedicated {{FlinkYarnSessionCli}} and with
the abstraction of {{CustomCommandLine}} things grow a lot on complexity... If
only we can have a unique entrypoint like {{SparkSubmit}} in Spark.
FYI {{CustomCommandLine}} also takes some responsibilities of configuration,
while some of ongoing effort try to make {{Configuration}} the unique interface
of configuration.

> Components: Client / Job Submission
> Reporter: Aljoscha Krettek
> Priority: Major
>
> Currently, "bin/flink run" supports both Java and Python programs and there
> is quite some complexity in command line parsing and validation and the code
> is spread across different classes.
> I think if we had a separate "bin/flink runpy" then we could simplify the
> parsing quite a bit and the usage help of each command would only show those
> options that are relevant for the given use case.
