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.

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

- 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`.

Also update the test to be simpler since we can use a mock event to simulate the issue
more easily (thanks Jun for the suggestion). This should fix two issues:
1. A transient test failure due to a NPE in ControllerFailoverTest.testMetadataUpdate:
```text
Caused by: java.lang.NullPointerException
at kafka.controller.ControllerBrokerRequestBatch.addUpdateMetadataRequestForBrokers(ControllerChannelManager.scala:338)
at kafka.controller.KafkaController.sendUpdateMetadataRequest(KafkaController.scala:975)
at kafka.controller.ControllerFailoverTest.testMetadataUpdate(ControllerFailoverTest.scala:141)
```
The test was creating an additional thread and it does not seem like it was doing the
appropriate synchronization (perhaps this became more of an issue after we changed
the Controller to be single-threaded and changed the locking)
2. Setting `activeControllerId.set(-1)` in `triggerControllerMove` causes `Reelect` not to invoke `onControllerResignation`. Among other things, this causes an `IllegalStateException` to be thrown when `KafkaScheduler.startup` is invoked for the second time without the corresponding `shutdown`. We now simply call `onControllerResignation` as part of `triggerControllerMove`.
Finally, I included a few clean-ups:
1. No longer update the broker state in `onControllerFailover`. This is no longer needed
since we removed the `RunningAsController` state (KAFKA-3761).
2. Trivial clean-ups in KafkaController
3. Removed unused parameter in `ZkUtils.getPartitionLeaderAndIsrForTopics`

Here is the sketch of this proposal:
1. When it is time to send the txn markers, only look for the leader node of the partition once instead of retrying, and if that information is not available, it means the partition is highly likely been removed since it was in the cache before. In this case, we just remove the partition from the metadata object and skip putting into the corresponding queue, and if all partitions' leader broker are non-available, complete this delayed operation to proceed to write the complete txn log entry.
2. If the leader id is unknown from the cache but the corresponding node object with the listener name is not available, it means that the leader is likely unavailable right now. Put it into a separate queue and let sender thread retry fetching its metadata again each time upon draining the queue.
One caveat of this approach is the delete-and-recreate case, and the argument is that since all the messages are deleted anyways when deleting the topic-partition, it does not matter whether the markers are on the log partitions or not.

Before this patch the consumer would return the cached offsets for partitions in its current assignment. This worked when all the offset commits went through the consumer.
With KIP-98, offsets can be committed transactionally through the producer. This means that relying on cached positions in the consumer returns incorrect information: since commits go through the producer, the cache is never updated.
Hence we need to update the `KafkaConsumer.committed` method to always lookup the server for the last committed offset to ensure it gets the correct information every time.

This ticket is all about ControllerContext initialization and teardown. The key points are:
1. we should teardown ControllerContext during resignation instead of waiting on election to fix it up. A heapdump shows that the former controller keeps pretty much all of its ControllerContext state laying around.
2. we don't properly teardown/reset ControllerContext.partitionsBeingReassigned. This can cause problems when the former controller becomes re-elected as controller at a later point in time.
Suppose a partition assignment is initially R0. Now suppose a reassignment R1 gets stuck during controller C0 and an admin tries to "undo" R1 (by deleting /admin/partitions_reassigned, deleting /controller, and submitting another reassignment specifying R0). The new controller C1 may succeed with R0. If the controller moves back to C0, it will then reattempt R1 even though that partition reassignment has been cleared from zookeeper prior to shifting the controller back to C0. This results in the actual partition reassignment in zookeeper being unexpectedly changed back to R1.

Two major changes plus one minor change:
0. change stateLock to a read-write lock.
1. Put the check of "isCoordinator" and "coordinatorLoading" together with the return of the metadata, under one read lock block, since otherwise we can get incorrect behavior if there is a change in the metadata cache after the check but before the accessing of the metadata.
2. Grab the read lock right before trying to append to local txn log, and until the local append returns; this is to avoid the scenario that the epoch has actually changed when we are appending to local log (e.g. emigration followed by immigration).
3. only watch on txnId instead of txnId and txnPartitionId in the txn marker purgatory, and disable reaper thread, as we can now safely clear all the delayed operations by traversing the marker queues.

With this patch, offset commits are always materialized according to the order of the commit records in the offsets topic.
Before this patch, transactional offset commits were materialized in transaction order. However, the log cleaner will always preserve the record with the greatest offset. This meant that if there was a mix of offset commits from a consumer and a transactional producer, then it we would switch from transactional order to offset order after cleaning, resulting in an inconsistent state.
