org.testcontainers.kafka.KafkaContainer is not reusable

[cer]

I discovered that kafka.KafkaContainer is not reusable.
As far as I can tell, it's because of the configure() method:

testcontainers-java/modules/kafka/src/main/java/org/testcontainers/kafka/KafkaContainer.java

Line 70 in cb7a793

withEnv("KAFKA_CONTROLLER_QUORUM_VOTERS", controllerQuorumVoters);

The value of KAFKA_CONTROLLER_QUORUM_VOTERS uses the random network alias generated by GenericContainer's constructor.

Is there a reason why it doesn't simply use localhost?

Thoughts?

Also, while investigating this issue, I discovered that if a container is reused its (newly generated) default network alias is not a network alias of the running container.
