What should this feature add?

Add a config setting auto_start_queue to invokeai.yaml to control whether the queue starts processing immediately on startup, and/or empty_queue_on_startup to empty the queue on startup.

In this discord bug report, the application had a catastrophic failure with a particular kind of queue item. This failure didn't give the app a chance to handle the error, it just immediately crashed. On next startup, that one queue item was pruned. The user would need to restart the app N number of times, where N is the number of problematic queue items, to clear the queue.

The proposed auto_start_queue would give the user a chance to inspect and clear the queue on startup before a crash-inducing queue item would be executed.

Or, empty_queue_on_startup would let the user get a fresh start.

I'm not sure which I prefer.
