KIP-122 added the ability for kafka-consumer-groups.sh to reset/change consumer offsets, at a fine grained level. This patch adds documentation for this feature.

In AK's documentation, the config props for connectors are not listed (https://kafka.apache.org/documentation/#connectconfigs). This PR adds these sink and source connector configs to the html site-docs.

Some sections of the Monitoring metrics documentation list out the -total metrics, and some sections do not list them out. Make them consistent and list out the missing -total metrics.

ZooKeeper client from version 3.4.13 doesn't handle connections to localhost very well. If ZooKeeper is started on 127.0.0.1 on a machine that has both ipv4 and ipv6 and a client is created using localhost rather than the IP address in the connection string, ZooKeeper client attempts to connect to ipv4 or ipv6 randomly with a fixed one second backoff if connection fails. Use 127.0.0.1 instead of localhost in streams tests to avoid intermittent test failures due to ZK client connection timeouts if ipv6 is chosen in consecutive address selections. Also add note to upgrade docs for 2.0.0.

1. Rename metrics scope of rocksDB window and session stores; also modify the store metrics accordingly with guidance on its correlations to metricsScope.
2. Add the missing total metrics for per-thread, per-task, per-node and per-store sensors.

This patch contains the improved offset expiration semantics proposed in KIP-211. Committed offsets will not be expired as long as a group is active. Once all members have left the group, then offsets will be expired after the timeout configured by `offsets.retention.minutes`. Note that the optimization for early expiration of unsubscribed topics will be implemented in a separate patch.
- Removed Scala consumers (`SimpleConsumer` and `ZooKeeperConsumerConnector`)
and their tests.
- Removed Scala request/response/message classes.
- Removed any mention of new consumer or new producer in the code
with the exception of MirrorMaker where the new.consumer option was
never deprecated so we have to keep it for now. The non-code
documentation has not been updated either, that will be done
separately.
- Removed a number of tools that only made sense in the context
of the Scala consumers (see upgrade notes).
- Updated some tools that worked with both Scala and Java consumers
so that they only support the latter (see upgrade notes).
- Removed `BaseConsumer` and related classes apart from `BaseRecord`
which is used in `MirrorMakerMessageHandler`. The latter is a pluggable
interface so effectively public API.
- Removed `ZkUtils` methods that were only used by the old consumers.
- Removed `ZkUtils.registerBroker` and `ZKCheckedEphemeral` since
the broker now uses the methods in `KafkaZkClient` and no-one else
should be using that method.
- Updated system tests so that they don't use the Scala consumers except
for multi-version tests.
- Updated LogDirFailureTest so that the consumer offsets topic would
continue to be available after all the failures. This was necessary for it
to work with the Java consumer.
- Some multi-version system tests had not been updated to include
recently released Kafka versions, fixed it.
- Updated findBugs and checkstyle configs not to refer to deleted
classes and packages.

Support configuration of dynamic broker configs in ZooKeeper before starting brokers using ConfigCommand. This will allow password configs to be encrypted and stored in ZooKeeper, without requiring clear passwords in server.properties to bootstrap the broker first.

We might decide to drop certain message batches during down-conversion because older clients might not be able to interpret them. One such example is control batches which are typically removed by the broker if down-conversion to V0 or V1 is required. This patch makes sure the chunked down-conversion implementation is able to handle such cases.
The initial PR for KIP-290 #5117 added a new `ResourceNameType`, which was initially a field on `Resource` and `ResourceFilter`. However, follow on PRs have now moved the name type fields to new `ResourcePattern` and `ResourcePatternFilter` classes. This means the old name is no longer valid and may be confusing. The PR looks to rename the class to a more intuitive `resource.PatternType`.
@cmccabe also requested that the current `ANY` value for this class be renamed to avoid confusion. `PatternType.ANY` currently causes `ResourcePatternFilter` to bring back all ACLs that would affect the supplied resource, i.e. it brings back literal, wildcard ACLs, and also does pattern matching to work out which prefix acls would affect the resource. This is very different from the behaviour of `ResourceType.ANY`, which just means the filter ignores the type of resources.
`ANY` is to be renamed to `MATCH` to disambiguate it from other `ANY` filter types. A new `ANY` will be added that works in the same way as others, i.e. it will cause the filter to ignore the pattern type, (but won't do any pattern matching).

This patch changes the default `request.timeout.ms` of the consumer to 30 seconds. Additionally, it adds logic to `NetworkClient` and related to components to support timeouts at the request level. We use this to handle the special case of the JoinGroup request, which may block for as long as the value configured by `max.poll.interval.ms`.

Adds a configuration that specifies the default timeout for KafkaConsumer APIs that could block. This was introduced in KIP-266.

Keep Literal ACLs on the old paths, using the old formats, to maintain backwards compatibility.
Have Prefixed, and any latter types, go on new paths, using JSON, (old brokers are not aware of them)
Add checks to reject any adminClient requests to add prefixed acls before the cluster is fully upgraded.

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.
