It takes O(n^2) time to instantiate a mbean with n attributes which can be very slow if the number of attributes of this mbean is large. This PR removes metrics whose number of attributes can grow with the number of partitions in the cluster to fix the performance issue. These metrics have already been marked for removal in 2.0 by KIP-225.

This PR actually contains two changes:
1. leverage on the TOPOLOGY_OPTIMIZATION config to "adjust" the topology internally to reuse the source topic.
2. fixed a long dangling bug that whenever source topic is reused as changelog topic, write the checkpoint file for the consumed offset, this is done by union the ackedOffset from the producer, plus the consumed offset from the consumer, note we will priori ackedOffset since the same topic may show up in both (think about repartition topic), by doing this the consumed offset from source topics can be treated as checkpointed offset when reuse happens.
3. added a few unit and integration tests with / wo the reusing, and make sure the restoration, standby task, and internal topic creation behaviors are all correct.

In BrokerCompatibilityTest.java, when older versioned broker is used (0.10.1, 0.10.2), LIST_OFFSET is not supported as well. Hence in the verification phase, there is a possibility that consumer hit the UnsupportedVersionException earlier than Streams actually hits it:
org.apache.kafka.common.errors.UnsupportedVersionException: The broker does not support LIST_OFFSETS with version in range [2,3]. The supported range is [0,1].
While the test is waiting for
org.apache.kafka.common.errors.UnsupportedVersionException: Cannot create a v0 FindCoordinator request because we require features supported only in 1 or later.
Both are valid errors to expect (the former is from consumer while the latter is from producer of the streams app).

If the property `errors.deadletterqueue.context.headers.enable` is set to true, add a set of headers to the message describing the context under which the error took place.
A unit test is added to check the correctness of header creation.

This is a follow-on change requested as part of the initial PR for KIP-290 #5117. @cmccabe requested that the `resource.Resource` class be factored out in favour of `ConfigResource` to avoid confusion between all the `Resource` implementations.

Currently, a throttled fetch response is returned with INVALID_SESSION_ID, which causes dropping the current fetch session if incremental fetch is in progress. This patch fixes this by returning the correct session id.

remove duplicate Scala ResourceNameType in preference to in preference to Java ResourceNameType.
This is follow on work for KIP-290 and PR #5117, which saw the Scala ResourceNameType class introduced.
I've added tests to ensure AclBindings can't be created with ResourceNameType.ANY or UNKNOWN.
Reviewers: Colin Patrick McCabe <colin@cmccabe.xyz>, Jun Rao <junrao@gmail.com>
The initial PR for KIP-290 #5117 added a `ResourceNameType` field to the Java and Scala `Resource` classes to introduce the concept of Prefixed ACLS. This does not make a lot of sense as these classes are meant to represent cluster resources, which would not have a concept of 'name type'. This work has not been released yet, so we have time to change it.
This PR looks to refactor the code to remove the name type field from the Java `Resource` class. (The Scala one will age out once KIP-290 is done, and removing it would involve changes to the `Authorizer` interface, so this class was not touched).
This is achieved by replacing the use of `Resource` with `ResourcePattern` and `ResourceFilter` with `ResourceFilterPattern`. A `ResourcePattern` is a combination of resource type, name and name type, where each field needs to be defined. A `ResourcePatternFilter` is used to select patterns during describe and delete operations.
The adminClient uses `AclBinding` and `AclBindingFilter`. These types have been switched over to use the new pattern types.
The AclCommands class, used by Kafka-acls.sh, has been converted to use the new pattern types.
The result is that the original `Resource` and `ResourceFilter` classes are not really used anywhere, except deprecated methods. However, the `Resource` class will be used if/when KIP-50 is done.

Currently, the replication factor is hardcoded to a value of 3. This means that we cannot use a DLQ in any cluster setup with less than three brokers. It is better to have the user specify this value if the default value does meet the requirements.

PrincipalBuilder implementations can now take the listener into account
when creating the Principal. This is especially interesting in deployments
where inter-broker traffic is on a different listener than client traffic or
when the same protocol is used by multiple listeners.
The change in itself is mostly "plumbing" as the listener name needs to be
passed from ChannelBuilders all the way down to all classes implementing
AuthenticationContext.

We added logic to reassign nodes in callToSend after a connection failure, but we do not handle the case when there is no node currently available to reassign the request to. This can happen when using MetadataUpdateNodeIdProvider if all of the known nodes are blacked out awaiting the retry backoff. To fix this, we need to ensure that the call is added to pendingCalls if a new node cannot be found.
