--------------------------------------
Hi Jonathan,
TestUtils.createBrokerConfigs() is usually used when the test class is
inheriting from KafkaServerTestHarness, which already handles server creation
and shutdown at setUp() and tearDown() time; TestUtils.createServer() should
then be used otherwise, i.e. when a broker is just needed to be created on the
fly.
TestUtils.createBrokersInZk() is different, though, in that it does not
actually create a running server, but just create the registration znode in ZK,
the Broker object is just a placeholder for the broker metadata, like broker
id, address, etc. They should only be used when we just need to test some
ZK-based utilities but do not necessarily need to really create a running
server.
> Replace AdminUtils.createOrUpdateTopicPartitionAssignmentPathInZK with
> TestUtils.createTopic in all unit tests
