Flaky test testPollThrowsInterruptExceptionIfInterrupted for new consumer

KafkaConsumerTest.testPollThrowsInterruptExceptionIfInterrupted is flaky for the new consumer (passing consistently for the classic consumer).

Fails with: 

org.opentest4j.AssertionFailedError: Expected org.apache.kafka.common.errors.InterruptException to be thrown, but nothing was thrown.

It's been flaky since enabled for the new consumer recently

Note that a very similar test already exist in AsyncKafkaConsumerTest.
testPollThrowsInterruptExceptionIfInterrupted, written specifically for the async consumer, and that passes consistently.
