> Current (old) masters only support quota guarantee which also servers as limits implicitly. When upgrading to new masters where guarantees and limits are decoupled, we need to ensure backward compatibility such that the existing (old) quota configurations are honored and there should be no change to the cluster behavior.
> To this end, new masters should also be able to consume the old quota registry. The old guarantee field will be used to set both guarantee and limits.
