Review comment:
Shall we standardize the characterset for all BeamFileSystemArtifact**** ?

> Portable Flink runner JobService entry point in a Docker container
> ------------------------------------------------------------------
>
> Key: BEAM-4130
> URL: https://issues.apache.org/jira/browse/BEAM-4130
> Project: Beam
> Issue Type: New Feature
> Components: runner-flink
> Reporter: Ben Sidhom
> Priority: Minor
> Time Spent: 1h
> Remaining Estimate: 0h
>
> The portable Flink runner exists as a Job Service that runs somewhere. We
> need a main entry point that itself spins up the job service (and artifact
> staging service). The main program itself should be packaged into an uberjar
> such that it can be run locally or submitted to a Flink deployment via `flink
> run`.
