[BEAM-483] Move NormalizedUniqueName to ApplicationNameOptions
----
> Generated job names easily collide

> Key: BEAM-483
> URL: https://issues.apache.org/jira/browse/BEAM-483
> Project: Beam
> Issue Type: Bug
> Components: runner-dataflow
> Reporter: Pei He
> Assignee: Pei He
> Priority: Minor
>
> The current job name generation scheme may easily lead to duplicate job names
> and cause DataflowJobAlreadyExistsException, especially when a series of jobs
> are submitted at the same time. (e.g., from a single script).
> It would be better to just add a random suffix like "-3275" or "-x1bh".
