PackageUtil: preserve classpath ordering when uploading
Also add a test
----
> Improve performance when staging files
> --------------------------------------

> Key: BEAM-814
> URL: https://issues.apache.org/jira/browse/BEAM-814
> Project: Beam
> Issue Type: Improvement
> Components: runner-dataflow
> Reporter: Daniel Halperin
> Assignee: Daniel Halperin
> Priority: Minor
> Fix For: 0.5.0
>
>
> Right now, {{PackageUtil}} hashes/compresses/sizes files, checks if they have
> already been staged, and uploads them if not, completely serially.
> There is some low-hanging fruit to parallelize this.
