[FLINK-3980] [core] Remove ExecutionConfig.PARALLELISM_UNKNOWN
----
> Remove ExecutionConfig.PARALLELISM_UNKNOWN
> ------------------------------------------
>
> Key: FLINK-3980
> URL: https://issues.apache.org/jira/browse/FLINK-3980
> Project: Flink
> Issue Type: Improvement
> Components: Core
> Affects Versions: 1.1.0
> Reporter: Greg Hogan
> Assignee: Greg Hogan
> Priority: Minor
> Fix For: 1.1.0
>
>
> FLINK-3589 added {{ExecutionConfig.PARALLELISM_DEFAULT}} and
> {{ExecutionConfig.PARALLELISM_UNKNOWN}}. The former gave a name to the
> contant {{-1}} and the latter was used as a default no-op when setting the
> parallelism.
> It's nice to keep these intents separate but given the current implementation
> of Operator parallelism users can get by using {{PARALLELISM_DEFAULT}}.
