    [FLINK-2686] Show exchange mode in JSON plan

    Extends the PlanJSONDumpGenerator to also include the Data Exchange mode. It will be shown like this:
    
    ```
    ...
    "parallelism": "2",
    "predecessors": [
    	{"id": 5, "ship_strategy": "Forward", "exchange_mode": "PIPELINED"}
    ],
    "driver_strategy": "Map",
    ...
    ```

> The execution plan JSON (via {{env.getExecutionPlan()}}) contains no information about the data exchange mode of the used channels.
> I think this would be super helpful while debugging problems like FLINK-2685. The channel types should also be considered in the plan rendering, but that's a separate issue.
