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

yes, this metric get obvious significance,  we develop a platform and serve 
many people , they often talk to me “ when job failed, and when job restore 
from cp” .  

> Add a system metric to show the checkpoint restore time

> Now the system metric only shows the downtime when failure happens. It would 
> be interesting to see the time to restore the checkpoint, so users can better 
> understand the bottleneck of failure recovery.
