This pr simplifies the subsystem jobs interface. Instead of requiring an extra message that is used to signal that a job should be ended, a job now ends when the receiver returns `None`. Besides that it changes the interface to enforce that messages to a job provide a relay parent.

There was a problem hiding this comment.
This makes ToJobTrait a bit more rigid: it ensures that we'll never write a subsystem using this util which can have jobs not tied to relay parents.
I think this is a reasonable simplification at this point.
We always convert this message to FromJobCommand anyway.
