-  <strong>Client quotas:</strong> Kafka supports different types of (per-user principal) client quotas. Because a client's quotas apply irrespective of which topics the client is writing to or reading from, they are a convenient and effective tool to allocate resources in a multi-tenant cluster. <a href="#design_quotascpu">Request rate quotas</a>, for example, help to limit a user's impact on broker CPU usage by limiting the time a broker spends on the <a href="/protocol.html">request handling path</a> for that user, after which throttling kicks in. In many situations, isolating users with request rate quotas has a bigger impact in multi-tenant clusters than setting incoming/outgoing network bandwidth quotas, because excessive broker CPU usage for processing requests reduces the effective bandwidth the broker can serve. Furthermore, administrators can also define quotas on topic operations—such as create, delete, and alter—to prevent Kafka clusters from being overwhelmed by high
 ly concurrent topic operations (see <a href="https://cwiki.apache.org/confluence/display/KAFKA/KIP-599%3A+Throttle+Create+Topic%2C+Create+Partition+and+Delete+Topic+Operations">KIP-599</a> and the quota type <code>controller_mutations_rate</code>).

Review Comment:
   Hard to see the change, which is on the last line: changes `controller_mutations_rate` to `controller_mutation_rate` since the latter is what was implemented despite what the KIP says.
