Here are the list of changes we made in this pull request. Top 3 are the principle changes, others are following these principles.
1. New agent and mesh report protocol.
2. New agent header protocol.
3. Service register, instance register and network address register have been removed permanently.
4. Service traffic, instance traffic and network alias metrics are added to replace the service, instance and network address inventory.
5. Register process has been removed.
6. Metrics stream process supports insert only mode, especially for traffic entities.
7. Metrics stream process supports no-downsampling mode for traffic entities and network alias.
8. Remove all register mechanism and cache in the java agent.
9. Remove MONTH step in GraphQL query.
10. Update UI to remove MONTH step query, the max query range is 60 days now.
11. Simplify the TTL to metrics and record. And the unit has been formatted in Day unit. No specific TTL for ElasticSearch storage.
12. Buffer mechanism of trace receiver and mesh receiver has been removed due to no register.
13. New service id, instance id and endpoint id rules, including service relation, instance relation and endpoint relation id rules.
14. Java agent support `keep tracing` mode, meaning, agent generating tracing context even the backend is unconnected/unavailable.
15. Plugin test tool up to date, in order to support new protocol.
16. Plugin tests expected data files updated.
17. E2E tests updated.
18. Telemetry of Grafana config has been merged into one.
19. Documentation updates.
20. [TBD] InfluxDB storage implementation is not available, need @dmsolr to fix later, in order to reduce the master change block by this PR.

### Motivation
Ease the efforts of modifying configurations in automatic workflow and scripts, like Docker and helm chart.
### Modification
Add a `selector` property into `application.yml` to enable switching configuration simply by environment variables or system properties, and filter the unselected options, leaving only selected one.
### Result
- We can switch a configuration by environment variables or system property
- Closes#4511
* Support dynamic column in the source.
* Support activeExtraModelColumns as a default OFF option.
* Fix words
* Update backend-setup.md
Fix format issue.
### Motivation:
Add test to guarantee that the components defined in class ComponentsDefine are in sync with those in file component-libraries.yml.
### Modifications:
- Add missing component in component-libraries.yml.
- Add test to verify the class and the yml are in sync.
- Fix wrong component id of Undertow.
### Result:
Components definitions in class ComponentsDefine and yaml are in sync, and will be verified in every pull request.
Motivation:
Review code styles with some bots automatically.
Modifications:
Set up ReviewDog in GitHub Action to review code style.
Add more check rules to checkstyle plugin.
Result:
Obvious code styles can be reviewed and commented automatically.
