* Update elasticsearch client 7.0.0 to elasticsearch client 7.5.0.
* Update CHANGES.md and LICENSE.

The current implementation of envoy ALS K8S analysis is based on the hierarchy, pod -> StatefulSet -> deployment, StatefulSet, or others. It's freaky and different from the Istio Kubernetes registry.

The new path is pod -> endpoint -> service, and we should leverage Informer API instead of raw Kubernetes API.

* Set up restrict length rules for service, instance and endpoint

* Adjust two env names.

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.

* Set the endpoint name length to 150, to keep safe and avoid over-length.

### 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
