> During config update, we apply new settings immediately.
> This can cause problems, because changes that are already applied are not reverted back when we encounter an error in {{Queue.applyConf()}}.
> Suggested approach:
> * Run through the hierarchy in a dry-run like fashion, to see if there's any error
> * If no error is returned, apply the new config
