Client-id based quota configuration overrides will continue be stored under /config/clients, but these will be applied only to clients of users without a quota override and only if default user quota is unlimited. Quota configuration overrides for user principals will be stored under /config/users. Note that url-encoded version of the user principal will be used as node name under /config/users to cope with Zookeeper naming restrictions. The non-encoded user principal will be stored as a property to make it easy to identify the actual user associated with the path. Quota overrides for clients of a user will be stored under /config/users/<user>/clients.
