    [FLINK-9598] Refine java-doc about the min pause between checkpoints

    ## What is the purpose of the change
    
    This pull request makes docs about config `minPauseBetweenCheckpoints` more 
clear, since many users felt confused about this config parameter as they found 
new checkpoint triggered once checkpoints failed, related threads:

> We have set the config Minimum Pause Between Checkpoints to be 10 min but 
> noticed that when a checkpoint fails (because it timesout before it 
> completes) the application immediately starts taking the next checkpoint. 
> This basically stalls the application's progress since its always taking 
> checkpoints.
> [^Screen Shot 2018-06-20 at 7.44.10 AM.png] is a screenshot of this issue.
> Details:
>  * Running Flink-1.3.2 on EMR
>  * checkpoint timeout duration: 40 min
>  * minimum pause between checkpoints: 10 min
> There is also a [relevant
