    [FLINK-5330] [tests] Harden KafkaConsumer08Test to fail reliably with unknown host exception

    Using static mocking to reliably fail the InetAddress.getByName call with an UnknowHostException.
    Furthermore, the PR decreases the connection timeouts which speeds the test execution
up.

> The {{KafkaConsumer08Test}} assumes that some of the Kafka bootstrap server hostname
cannot be resolved. This can lead to failures if these names are wrongly resolved by chance
(e.g. if using Google's DNS server). Moreover, the test cases take a long time to finish because
the connection timeouts are set to a high value. This can be decreased to speed these test
cases up.
