    KAFKA-4041: Update ZooKeeper to 3.4.13 (#5376)
    
    This includes a fix for ZOOKEEPER-2184 (Zookeeper Client
    should re-resolve hosts when connection attempts fail), which
    fixes KAFKA-4041.
    
    Updated a couple of tests as unresolvable addresses are now
    retried until the connection timeout. Cleaned up tests a little.
