`ChangeLoggingWindowBytesStore` needs to have the same `retainDuplicates` functionality as `RocksDBWindowStore` else data could be lost upon failover/restoration.

1. StreamThread: prevent `PARTITIONS_REVOKED` to transit to itself in `setState` by returning false. And only execute the task suspension logic when `setState(PARTITIONS_REVOKED)` returns true in `onPartitionsRevoked`.
2. StreamThread: minor, renaming `shutdown` to `completeShutdown`, and `close` to `shutdown`, `stillRunning` to `isRunning`, `isInitialized` to `isRunningAndNotRebalancing`.
3. GlobalStreamThread: tighten the transition a bit in `setState`. Force transiting to `PENDING_SHUTDOWN` and `DEAD` when initialization failed.
4. GlobalStreamThread: minor, add logPrefix to StateConsumer. Also removing its state change listener when closing the thread.
5. KafkaStreams: because of 1) above we can now prevent its `REBALANCING` to `REBALANCING`.
6. KafkaStreams: prevent `CREATED` to ever go to `REBALANCING` first to force it transit to `RUNNING` when starting. Also prevent `CREATED` to go to `ERROR`.
7. KafkaStreams: collapse `validateStartOnce` and `checkFirstTimeClosing ` into `setState`.
8. KafkaStreams: in `close` and `start`, only execute the logic when `setState` succeeds.

* When a call is aborted, that should count as a "try" in the failure log message.
* FailureInjectingTimeoutProcessorFactory should fail the first request it is asked about.
* testCallTimeouts should expect the first request it makes to fail because of the timeout we injected.
* FailureInjectingTimeoutProcessorFactory should track how many failures it has injected, and the test should verify that one has been injected.

Closes#3556 from jcustenborder/KAFKA-5620
If a task fails during initialization due to a LockException, its changelog partitions are not immediately added to the StoreChangelogReader as the thread doesn't hold the lock. However StoreChangelogReader#restore will be called and it sets the initialized flag. On a subsequent successfull call to initialize the new tasks the partitions are added to the StoreChangelogReader, however as it is already initialized these new partitions will never be restored. So the task would remain in a non-running state forever.

This patch contains a few small improvements to make request/response handling more consistent. Primarily it consolidates request/response serialization logic so that `SaslServerAuthenticator` and `KafkaApis` follow the same path. It also reduces the amount of custom logic needed to handle unsupported versions of the ApiVersions requests.

Closes#3634 from ijuma/fix-misleading-compact-log-config
This patch ensures that the consumer groupId and clientId are available in all log messages which makes debugging much easier when a single application has multiple consumer instances. To make this easier, I've added a new `LogContext` object which builds a log prefix similar to the broker-side `kafka.utils.Logging` mixin. Additionally this patch changes the log level for a couple minor cases:
- Consumer wakeup events are now logged at DEBUG instead of TRACE
- Heartbeat enabling/disabling is now logged at DEBUG instead of TRACE

Closes#3681 from guozhangwang/K5733-rocksdb-bulk-load
Prior to this change, it was possible for the synchronous consumer commit request to be handled before previously-submitted asynchronous commit requests. If that happened, the out-of-order handlers improperly set the last committed offsets, which then became inconsistent with the offsets the connector task is working with.
This change ensures that the last committed offsets are updated only for the most recent commit request, even if the consumer reorders the calls to the callbacks.
