> It is convenient for users to have a metric which tells you how long the 
> restarting of a job has taken.
> I propose a to introduce a {{Gauge}} which returns the time between 
> {{JobStatus.RESTARTING}} and {{JobStatus.RUNNING}}. If the job was not 
> restarted (initial run), then this metric will return {{-1}}.
