Instead of requiring iteration to be able to list new jobs and existing jobs so that they can be claimed, allow for attaching callbacks to the jobboard where instead of requiring iteration those callbacks will be automatically called by the jobboard internally when events are recieved. Breaking change: renames transition notifier to notifier since it is really not just a notifier for transitions but is a generic notifier of events occuring (and details about those events). This is an internal api so its not expected that this will cause any issues (it's not expected for external users to be creating instances of this class).
