Description

Currently we do not retry ListGroups requests when they fail due to retriable errors. For example, this is causing some instability in `kafka.admin.ListConsumerGroupTest.testListConsumerGroups`.

java.util.concurrent.ExecutionException: org.apache.kafka.common.errors.CoordinatorLoadInProgressException: Error listing groups on localhost:43001 (id: 0 rack: null)
	at org.apache.kafka.common.internals.KafkaFutureImpl.wrapAndThrow(KafkaFutureImpl.java:45)
	at org.apache.kafka.common.internals.KafkaFutureImpl.access$000(KafkaFutureImpl.java:32)
	at org.apache.kafka.common.internals.KafkaFutureImpl$SingleWaiter.await(KafkaFutureImpl.java:89)
	at org.apache.kafka.common.internals.KafkaFutureImpl.get(KafkaFutureImpl.java:262)
