> The JobInProgressListener interface is used by the framework to notify Schedulers of
when jobs are added, removed, or updated. Right now, there is no way for the Scheduler to
know that a job has completed. jobRemoved() is called when a job is retired, which can happen
many hours after a job is actually completed. jobUpdated() is called when a job's priority
is changed. We need to notify a listener when a job has completed (either successfully, or
has failed or been killed).
