    [FLINK-8626] Introduce BackPressureStatsTracker interface
    Renames BackPressureStatsTracker into BackPressureStatsTrackerImpl and introduce

    [FLINK-8546] [flip6] Respect savepoints and restore from latest checkpoints
    Let the JobMaster respect checkpoints and savepoints. The JobMaster will always
    try to restore the latest checkpoint if there is one available. Next it will check
    whether savepoint restore settings have been set. If so, then it will try to restore
    the savepoint. Only if these settings are not set, the job will be started from

    [FLINK-8629] [flip6] Allow JobMaster to rescale jobs
    This commit adds the functionality to rescale a job or parts of it to
    the JobMaster. In order to rescale a job, the JobMaster does the following:
    1. Take a savepoint
    2. Create a rescaled ExecutionGraph from the JobGraph
    3. Initialize it with the taken savepoint
    4. Suspend the old ExecutionGraph
    5. Restart the new ExecutionGraph once the old ExecutionGraph has been suspended
