Review comment:
I am wondering whether we could inject already constructed
`jobMasterService` at this point.
The code associated with the `user code` could be part of factory
(`libraryCacheManager.registerJob(...` and `userCodeLoader = ...`) making
`JobManagerRunner` constructor exception-free and having only dependence
assignments.
