feat: allow graceful shutdowns (#546)

Browse source 
Add a `Shutdown(context.Context) error` method to the Poller. Calling this method will first shutdown all active polling, preventing any new jobs from spawning. It will then wait for either all jobs to finish, or for the context to be cancelled. If the context is cancelled, it will then force all jobs to end, and then exit.
