`JarRunHandler` could use this method as well.

> Key: FLINK-9624
> URL: https://issues.apache.org/jira/browse/FLINK-9624
> Project: Flink
> Issue Type: Improvement
> Components: Job-Submission
> Affects Versions: 1.6.0
> Reporter: Chesnay Schepler
> Assignee: Chesnay Schepler
> Priority: Major
> Labels: pull-request-available
> Fix For: 1.6.0
>
>
> The {{JobGraph}} offers utility methods for uploading jars and artifacts to
> the BlobService.
> However, how these files are uploaded isn't a concern of the {{JobGraph}} but
> the submission-method, like the {{RestClusterClient}}.
> These methods should be moved into a utility class.
