> 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.
