Listen for queue events

[stayallive]

Using this in my own apps for some time, seems like a sane approach to do the following when working queue jobs:

• Send unsent errors as soon as a job is processed since another might take a while to come and the process may not end soon (so make sure all events are sent)
• Clear the breadcrumbs as soon as a job is processed and events have been sent so there is a clean breadcrumbs record instead of piling on crumbs
• Add an crumb to indicate which job started and add some metadata about the job

@Jean85 Does this seem like a good approach to take (conceptually)?
