commit 88ec4d0d60bcfd48e8ac7dcfe6072d0bf8538b23

    KAFKA-14259: BrokerRegistration#toString throws an exception, terminating 
metadata replay (#12681)
    
    Previously, BrokerRegistration#toString sould throw an exception, 
terminating metadata replay,
    because the sorted() method is used on an entry set rather than a key set.
