    Third time's the charm:
    * the time of the last triggered checkpoint is stored
    * when a checkpoint is triggered we check whether the interval has passed, if so we reschedule
the next checkpoint with a delay of minInterval
    * test added

> FLINK-3051 introduced already a filed in the {{CheckpointConfig}} to specify a min pause
between checkpoints.
> In high-load situations (big state), jobs might spend their entire time creating snapshots,
not processing data. With a min pause between checkpoints, users can guarantee that there
is a certain time-span the system can use for doing some actual data processing.
