Addressed review feedback by @dajac and @rajinisivaram
Ported from apache/kafka-site#334
Reviewers: Bill Bejeck <bbejeck@apache.org>
Add docs for KIP-663.
Reviewers: Jim Galasyn <jim.galasyn@confluent.io>, Walker Carlson <wcarlson@confluent.io>, Matthias J. Sax <matthias@confluent.io>
This adds a new user-facing documentation "Geo-replication (Cross-Cluster Data Mirroring)" section to the Kafka Operations documentation that covers MirrorMaker v2.
Was already merged to kafka-site via apache/kafka-site#324.

Document the new properties-based metrics for RocksDB

During the AK website upgrade, changes made to kafka-site weren't migrated back to kafka-docs.
This PR is an initial attempt at porting the changes to kafka/docs, but it does not include the streams changes. Those will come in a separate PR.
For the most part, the bulk of the changes in the PR are cosmetic. Only the introduction.html has substantial changes, but it's a direct port from the live documentation.
For testing:
I reviewed the PR diffs

Java 11 has been recommended for a while, but the ops section had not been updated.
Also added `-XX:+ExplicitGCInvokesConcurrent` which has been in `kafka-run-class`
for a while. Finally, tweaked the text slightly to read better.

1. fix typo: `atleast` -> `at least`
2. add missing `--` from `--bootstrap-servers` argument to be consistent
3. rephrase a sentence, to make it more clear:
before: `LinkedIn is currently running JDK 1.8 u5 (looking to upgrade to a newer version) with the G1 collector`
It will misguide the users to use JDK 1.8 u5, while the JDK 1.8 u251 is already released, which will include many important bug fixes. I did some rephrase as below:
after: `At the time this is written, LinkedIn is running JDK 1.8 u5 (looking to upgrade to a newer version) with the G1 collector`
Reviewers: Konstantine Karantasis <konstantine@confluent.io>
The href attribute missed the starting double quote, so the hyperlink is interpreted as https://docs.oracle.com/.../agent.html", with a redundant tailing double quote.
Add the missing starting double quote back to fix this issue.

This patch modifies the loading time metric to account for time spent waiting for the loading time task to be scheduled.

Minor comments
This is the implementation for [KIP-503](https://cwiki.apache.org/confluence/display/KAFKA/KIP-503%3A+Add+metric+for+number+of+topics+marked+for+deletion)
When deleting a large number of topics, the Controller can get quite bogged down. One problem with this is the lack of visibility into the progress of the Controller. We can look into the ZK path for topics marked for deletion, but in a production environment this is inconvenient. This PR adds a JMX metric `kafka.controller:type=KafkaController,name=TopicsToDeleteCount` to make it easier to see how many topics are being deleted.

- Add metrics to provide visibility for how long group metadata and transaction metadata take to load in order to understand some inactivity seen in the consumer groups
- Tests include mocking load times by creating a delay after each are loaded and ensuring the measured JMX metric is as it should be

this PR will fix a typo related to docs:
http://kafka.apache.org/21/documentation.html#rep-throttle
```bash
$ bin/kafka-reassign-partitions.sh --zookeeper myhost:2181--execute --reassignment-json-file bigger-cluster.json —throttle 50000000
```
I think `myhost:2181` should be `localhost:2181` and followed by a `space`

Implemented an in-memory window store allowing for range queries. A finite retention period defines how long records will be kept, ie the window of time for fetching, and the grace period defines the window within which late-arriving data may still be written to the store.
Unit tests were written to test the functionality of the window store, including its insert/update/delete and fetch operations. Single-record, all records, and range fetch were tested, for both time ranges and key ranges. The logging and metrics for late-arriving (dropped)records were tested as well as the ability to restore from a changelog.

My top 2 reasons for visiting the Kafka docs are to:
- View configurations
- View metrics
This PR aims to improve the user experience for viewing metrics:
- Add href links to the `Monitoring` section of the Table of Contents so users do not need to scroll or Ctrl/Cmd-F to find specific metric details (Monitoring section has grown large as more component & metrics are added)

KIP-368 implementation to enable periodic re-authentication of SASL clients. Also adds a broker configuration option to terminate client connections that do not re-authenticate within the configured interval.
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.

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.
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.

* Set --source, --target and --release to 1.8.
* Build Scala 2.12 by default.
* Remove some conditionals in the build file now that Java 8
is the minimum version.
* Bump the version of Jetty, Jersey and Checkstyle (the newer
versions require Java 8).
* Fixed issues uncovered by the new version if Checkstyle.
* A couple of minor updates to handle an incompatible source
change in the new version of Jetty.
* Add dependency to jersey-hk2 to fix failing tests caused
by Jersey upgrade.
* Update release script to use Java 8 and to take into account
that Scala 2.12 is now built by default.
* While we're at it, bump the version of Gradle, Gradle plugins,
ScalaLogging, JMH and apache directory api.
* Minor documentation updates including the readme and upgrade
notes. A number of Streams Java 7 examples can be removed
subsequently.
Add docs for the ReplicationBytesInPerSec and ReplicationBytesOutPerSec metrics. These metrics were introduced in KIP-153 (KAFKA-5194) but the docs were not updated.
Built site-docs, and viewed them in a web browser to confirm.
