These are the following improvements I made:
1. On stream thread level, INFO will be demonstrating `Completed xx tasks in yy ms` or `Completed rebalance with xx state in yy ms`,
2. On Stream thread cache level, INFO on `Flushed xx records`.
3. On Stream thread level, DEBUG on internal batched operations like `created xx tasks`, and TRACE on individual operation like `created x task`.
4. Also using `isTraceEnabled` on the critical path to reduce overhead of creating `Object[]`.
5. Minor cleanups in the code.

During a broker rolling upgrade, it's likely we don't have enough brokers ready yet. If streams does not need to create a topic it shouldn't check how many brokers are up.

In the event of a crash, we always restore the data from the backing changelog. So it seems that we don't need to
persist all data to disk by calling flush when committing. Frequent flushing leads to a large number of small files for compaction increasing
compaction pressure. This PR will perform benchmarks to see if there is any performance gain in not calling `flush()` each time we commit.

Closes#3288 from jeyhunkarimov/KAFKA-4661
Originally we assume the task will be created exactly three times (twice upon starting up, once for each thread, and then one more time when rebalancing upon the thread failure). However there is a likelihood that upon starting up more than one rebalance will be triggered, and hence the tasks will be initialized more than 3 times, i.e. there will be more than three hashcodes of the `Transformer` object, causing the `errorInjected` to never be taken and exception never thrown.
The current fix is to use an atomic boolean instead and let threads compete on compare-and-set to make sure exactly one thread will throw exception, and will only throw once.
Without this patch I can reproduce the issue on my local machine with a single core ever 3-5 times; with this patch I have been running successfully for 10+ runs.

Closes#3172 from guozhangwang/K5350-compatibility-annotations
- Added a boolean `allow_auto_topic_creation` to MetadataRequest and
bumped the protocol version to V4.
- When connecting to brokers older than 0.11.0.0, the `allow_auto_topic_creation`
field won't be considered, so we send a metadata request for all topics
to keep the behavior consistent.
- Set `allow_auto_topic_creation` to false in the new AdminClient and
StreamsKafkaClient (which exists for the purpose of creating topics
manually); set it to true everywhere else for now. Other clients will eventually
rely on client-side auto topic creation, but that’s not there yet.
- Add `allowAutoTopicCreation` field to `Metadata`, which is used by
`DefaultMetadataUpdater`. This is not strictly needed for the new
`AdminClient`, but it avoids surprises if it ever adds a topic to `Metadata`
via `setTopics` or `addTopic`.
