/**
* Utility class to store job information on the [[JobManager]]. The JobInfo stores which actor
* submitted the job, when the start time and, if already terminated, the end time was.
* Additionally, it stores whether the job was started in the detached mode. Detached means that
* the submitting actor does not wait for the job result once the job has terminated.
*
* Important: This class is serializable, but needs to be deserialized in the context of an actor
* system in order to resolve the client [[ActorRef]]. It is possible to serialize the Akka URL
* manually, but it is cumbersome and complicates testing in certain scenarios, where you need to
* make sure to resolve the correct [[ActorRef]]s when submitting jobs (RepointableActorRef vs.
* RemoteActorRef).
*
* @param client Actor which submitted the job
* @param start Starting time
