In `TransationStateManager`, we reset the pending state if an error occurred while appending to log; this is correct except that for the `TransactionMarkerChannelManager`, as it will retry appending to log and if eventually it succeeded, the transaction metadata's completing transition will throw an IllegalStateException since pending state is None, this will be thrown all the way to the `KafkaApis` and be swallowed.
1. Do not reset the pending state if the append will be retried (as is the case when write the complete transition).
2. A bunch of log4j improvements based the debugging experience. The main principle is to make sure all error codes that is about to sent to the client will be logged, and unnecessary log4j entries to be removed.
3. Also moved some log entries in ReplicationUtils.scala to `trace`: this is rather orthogonal to this PR but I found it rather annoying while debugging the logs.
4. A couple of unrelated bug fixes as pointed by hachikuji and apurvam.

This assertion is hard to get right because the system time can roll backward on a host due to NTP (as shown in the ticket), and also because a transaction can start on one host and complete on another. Getting precise clock times across hosts is virtually impossible, and this check makes things fragile.

`DescribeConsumerGroupTest#testDescribeExistingGroupWithNoMembersWithNewConsumer` shuts down the consumer executor thread and then checks that the assignments returned by `describeGroup` contain the consume group with no members. But if the executor thread is shut down before any offsets are committed, the assignments returned by `describeGroup` doesn't contain the group at all. This PR waits for an offset commit by waiting for the group to appear in `describeGroup` assignments prior to shutting down the executor.

This should fix transient failures due to timeouts caused by slow
auto creation of the offsets topic. The one exception is
`testDescribeGroupWithNewConsumerWithShortInitializationTimeout` where
we want initialisation to take longer than the timeout so we let
it be auto created. That test has also been a bit flaky and I reduced
the timeout to 1 ms.
Also:
- Simplified resource handling
- Removed usage of EasyMock that didn't make sense.
- `findCoordinator` should retry if `sendAnyNode` throws an exception

In the `AddPartitionsToTxn` request handling, if even one partition fails authorization checks, the entire request is essentially failed. However, the `AddPartitionsToTxnResponse` today will only contain the error codes for the topics which failed authorization. It will have no error code for the topics which succeeded, making it inconsistent with other APIs.
This patch adds a new error code `OPERATION_NOT_ATTEMPTED` which is returned for the successful partitions to indicate that they were not added to the transaction.

Closes#3204 from apurvam/KAFKA-5322-add-operation-not-attempted-for-add-partitions
We had originally increased Snappy’s block size as part of KAFKA-3704. However,
we had some issues with excessive memory usage in the producer and we reverted
it in 7c6ee8d5e.
After more investigation, we fixed the underlying reason why memory usage seemed
to grow much more than expected via KAFKA-3747 (included in 0.10.0.1).
In 0.10.2, we changed the broker to use the same classes as the producer and the
broker’s block size for Snappy was changed from 32 KB to 1KB. As reported in
KAFKA-5236, the on disk size is, in some cases, 50% larger when the data is compressed
with 1 KB instead of 32 KB as the block size.
As discussed in KAFKA-3704, it may be worth making this configurable and/or allocate
the compression buffers from the producer pool. However, for 0.11.0.0, I think the
simplest thing to do is to default to 32 KB for Snappy (the default if no block size
is provided).
I also increased the Gzip buffer size. 1 KB is too small and the default is smaller
still (512 bytes). 8 KB (which is the default buffer size for BufferedOutputStream)
seemed like a reasonable default.

This PR updates processing of console consumer's input properties.
For both old and new consumer, the value provided for `auto.offset.reset` indirectly through `consumer.config` or `consumer.property` arguments will now take effect.
For new consumer and for `key.deserializer` and `value.deserializer` properties, the precedence order is fixed to first the value directly provided as an argument, then the value provided indirectly via `consumer.property` and then `consumer.config`, and finally a default value.

More specifically, V2 messages are always batched (whether compressed or not) while
V0/V1 are only batched if they are compressed.
Clients like librdkafka expect to receive messages from the fetch offset when dealing with uncompressed V0/V1 messages. When converting from V2 to V0/1, we were returning all the
messages in the V2 batch.

- 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`.
