We intended to make `KafkaConsumer.close()` idempotent,
but due to the fact that the `closed` variable is
checked without a lock prior to beginning close logic,
it is possible for two or more threads to see
`closed=false` and attempt to close.

Before 0.11, we used to have limits for maximum message size on the producer, broker, and consumer side.
From 0.11 onward, these limits apply to record batches as a whole. This patch updates the documentation of the configs to make this explicit.
A separate patch will have more extensive upgrade notes to tie all the changes together in one narrative.

The actual fix for KAFKA-5490 is in
https://github.com/apache/kafka/pull/3406.
This is just the consumer change that will allow the cleaner
to use empty record batches without breaking 0.11.0.0
consumers (assuming that KAFKA-5490 does not make the cut).
This is a safe change even if we decide to go with a different option
for KAFKA-5490 and I'd like to include it in RC2.

* 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.

Closes#3053 from smccauliff/kafka-5239
If producer creates a connection during Kerberos re-login (after logout,
before login), there are no principals in the subject and
`SaslClientAuthenticator.configure` may throw an exception while trying
to determine the principal. A socket channel is created and its key
registered with the selector, but the `RuntimeException` thrown leaves
the key registered with the selector without adding the channel to the
channel list. This results in an infinite loop of `NullPointerExceptions`.
The PR applies two fixes:
1. Convert the `RuntimeException` to a meaningful `KafkaException`
2. Handle any exception in `buildChannel`, cleanup and throw `IOException`.
Retries will take care of re-connections.
