KAFKA-18794: Disable flaky tests pending investigation (apache#19340)

KafkaShareConsumerTest is proving very flaky. The behaviour of
MockClient does not appear to match the expectations of the test. This
PR disables the flaky tests to reduce build noise. When a proper
solution has been worked out, the tests can be re-enabled.
