--------------------------------------

Hi [~Feifan Wang], I've assigned the ticket to you. Before you start coding 
could you quickly explain how you intend to solve the problem (e.g. which REST 
parameters to add, whether to add a CLI option and if yes what's its name?).

> Specify a separate savepoint timeout option via CLI

> Savepoint can take much longer time to perform than checkpoint, especially 
> with incremental checkpoint enabled. This leads to a couple of troubles:
>  * For our job, we currently have to set the checkpoint timeout much large 
> than necessary, otherwise we would be unable to perform savepoint. 
>  * During rush hour, our cluster would encounter high rate of checkpoint 
> timeout due to backpressure, however we're unable to migrate to a larger 
> configuration, because savepoint also timeout.
> In my opinion, the timeout for savepoint should be configurable separately, 
> both in the config file and as parameter to the savepoint command.
