[RFC] Allow dynamic config & respect namespace declarations in umbrella apps

[nickegg]

The current worker supervisor does not allow for dynamic supervision on an per app basis resulting in each app subscribing to all queues. The worker supervisor currently pulls in all configs and creates workers for all. If there was a way to respect the namespace declaration for queues and hosts each app would be able to only subscribe to certain queues it cares about.

➕ 1 on this!

A lot of libraries allow configuration via an init function that can define to provide connection information.

This would be very helpful in TaskBunny. I'm having to do some hacky configuration stuff to do some mildly complex environment-specific configuration.
