kumo.on('get_queue_config', function(queue_name))

This event handler is in flux and may change significantly

Not the final form of this API, but this is currently how we retrieve configuration used for managing a queue.

kumo.on('get_queue_config', function(queue_name)
  return kumo.make_queue_config {
    max_retry_interval = 20 * 60,
  }
end)
