Before this patch, the `partitionErrors` was an immutable map. As a result if a single producer had a marker for multiple partitions, and if there were multiple response callbacks for a single append, we would get an `UnsupportedOperationException` in the `writeTxnMarker` handler.

When the message copier hangs (like when there is a bug in the client), it ignores the sigterm and doesn't shut down. this leaves the cluster in an unclean state causing future tests to fail.
In this patch we always send SIGKILL when cleaning the node if the process isn't already dead. This is consistent with the other services.

Closes#3284 from hachikuji/minor-either-usage-cleanup
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.

Closes#3286 from apurvam/KAFKA-5415-avoid-timestamp-check-in-completeTransition
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.

* NetworkClient.java: when trace logging is enabled, show AbstractResponse Struct objects, rather than just a memory address of the AbstractResponse.
* AclOperation.java: add documentation of what ACLs imply other ACLs.
* Resource.java: add CLUSTER, CLUSTER_NAME constants.
* Reconcile the Java and Scala classes for ResourceType, OperationType, etc. Add unit tests to ensure they can be converted to each other.
* AclCommand.scala: we should be able to apply ACLs containing Alter and Describe operations to Cluster resources.
* SimpleAclAuthorizer: update the authorizer to handle the ACL inheritance rules described in AclOperation.java.
* KafkaApis.scala: update createAcls and deleteAcls to use ALTER on CLUSTER, as described in the KIP. describeAcls should use DESCRIBE on CLUSTER. Use fromJava methods instead of fromString methods to convert from Java objects to Scala ones.
* SaslSslAdminClientIntegrationTest.scala: do not use AllowEveryoneIfNoAclIsFound. Add a configureSecurityBeforeServerStart hook which installs the ACLs necessary for the tests. Add a test of ACL authorization ALLOW and DENY functionality.

Closes#3240 from cmccabe/KAFKA-5292
Before this patch, we would call `producerBatch.done` directly from the accumulator when expiring batches. This meant that we would not transition to the `ABORTABLE_ERROR` state in the transaction manager, allowing other transactional requests (including Commits!) to go through, even though the produce failed.
This patch modifies the logic so that we call `Sender.failBatch` on every expired batch, thus ensuring that the transaction state is accurate.

The log_level parameter is used in system tests in kafka.py. However the log4j template accepted that parameter in only one place. This led to a large number of DEBUG lines printed even when the intention was to capture only INFO lines. Led to huge log files. Thanks to ijuma for noticing this.
