KAFKA-16627: Remove ClusterConfig parameter in BeforeEach and AfterEach

[brandboat]

related to KAFKA-16627

In the past we modify configs like server broker properties by modifying the ClusterConfig reference passed to BeforeEach and AfterEach based on the requirements of the tests.
While after KAFKA-16560, the ClusterConfig become immutable, modify the ClusterConfig reference no longer reflects any changes to the test cluster. Then pass ClusterConfig to BeforeEach and AfterEach become redundant.

This pr directly remove the behavior that pass ClusterConfig to all test methods and before/after each method.

@brandboat thanks for this patch. Could you also revise the following docs to remind developers that ClusterConfig is immutable now!!!

1. kafka/core/src/test/java/kafka/test/ClusterInstance.java

   Line 52 in 5de5d96

   ClusterConfig config();

2. kafka/core/src/test/java/kafka/test/junit/README.md

   Line 108 in 5de5d96

   * ClusterConfig: a mutable cluster configuration, includes cluster type, number of brokers, properties, etc
