What is the purpose of the change

[RIP-63] Issue #6567 .
Optimize the proxy's and client's selection strategy for brokers when sending messages, and use multiple selection strategies as a pipeline to filter suitable queues.

Brief changelog

Client:

Modified the files in org.apache.rocketmq.client.latency, such as MQFaultStrategy and LatencyFaultTolerance. These changes implemented queues's filters, which will provide more flexible selecting strategies.
Added some switches and configs in ClientConfig, to control this strategy.
Modified the updateFaultItem() method in the sending process. This method is designed to help record the brokers' available status. Now it will also record whether brokers are reachable or not.

Proxy:

Added the MQFaultStrategy in the topicRouteService. It will provide a similar queue selection mechanism in the client.
Added some switches and configs in ProxyConfig, to control this strategy.
Implemented the selectOneByPipeline() in MessageQueueSelector. It will call the filters in mqFaultStrategy to select suitable queue while sending messages.
Modified the implement of select() in SendMessageQueueSelector, now it will call the selectOneByPipeline(), but not the selectOne() before.(PS: If the switch is not opened, it will also run as selectOne()).
Added updateFaultItem() in the ProducerProcessor's sendMessage to record brokers' status, according to sending results.

Follow this checklist to help us incorporate your contribution quickly and easily. Notice, it would be helpful if you could finish the following 5 checklist(the last one is not necessary)before request the community to review your PR.

Make sure there is a Github issue filed for the change (usually before you start working on it). Trivial changes like typos do not require a Github issue. Your pull request should address just this issue, without pulling in other changes - one PR resolves one issue.
Format the pull request title like [ISSUE #123] Fix UnknownException when host config not exist. Each commit in the pull request should have a meaningful subject line and body.
Write a pull request description that is detailed enough to understand what the pull request does, how, and why.
Write necessary unit-test(over 80% coverage) to verify your logic correction, more mock a little better when cross module dependency exist. If the new feature or significant change is committed, please remember to add integration-test in test module.
Run mvn -B clean apache-rat:check findbugs:findbugs checkstyle:checkstyle to make sure basic checks pass. Run mvn clean install -DskipITs to make sure unit-test pass. Run mvn clean test-compile failsafe:integration-test to make sure integration-test pass.

OK, I will remove this design.

It seems more appropriate to write it like this:
private final static Logger log = LoggerFactory.getLogger(RemoteClientConfig.class);

Yes, It should be. But I think I will remove this RemoteClientConfig...
The switches in clientConfig are enough.

Use whenComplete is better. When an exception occurs, the upper layer function will get null in thenApply

Some methods need to be modified

There is no need to use AtomicLong for endTimestamp, just a local variable would be fine
