@tillrohrmann @StephanEwen sorry about the long delay here, would you
please take another look?
I followed Stephan's suggestion of not introducing a new method. However,
the semantics that I was shooting for with `initializeState` is that it would
be called on both _start_ and _restart_. I adjusted `JobManager` to call
`restoreLatestCheckpointedState` on first execution (as does `JobMaster`). Are
you OK with that?
