KAFKA-18225 ClientQuotaCallback#updateClusterMetadata is unsupported by kraft (#18196) 

This commit ensures that the ClientQuotaCallback#updateClusterMetadata method is executed in KRaft mode. This method is triggered whenever a topic or cluster metadata change occurs. However, in KRaft mode, the current implementation of the updateClusterMetadata API is inefficient due to the requirement of creating a full Cluster object. To address this, a follow-up issue (KAFKA-18239) has been created to explore more efficient mechanisms for providing cluster information to the ClientQuotaCallback without incurring the overhead of a full Cluster object creation.
