I've revisited this PR:
* ScheduledTrigger remains unchanged
* StreamEecutionEnvironment remains unchanged
* if the minIntervalBetweenCheckpoints is > 0 a different schedule method
is used
* scheduleAtFixedRate() is used when minInterval == 0. This is the current
behaviour, meaning checkpoints can build up if they aren't processed fast enough
* schedule() is used when minInterval > 0. New stuff right here. It
schedules the next checkpoint relative to the completion of the last. So we
just pop the interval as the period in there and are done.
