KAFKA-4633: Always using regex pattern subscription in StreamThread
1. In StreamThread, always use subscribe(Pattern, ..) function in order to
avoid sending MetadataRequest with specific topic names and cause brokers to
possibly auto-create subscribed topics; the pattern is generated as
"topic-1|topic-2..|topic-n".
2. Minor cleanup: changed String[] to List<String> to avoid overloaded
functions.
3. Minor cleanup: augmented unit test error message and fixed a potential
transient failure in KafkaStreamTest.
