Remove H2 as storage option permanently. BanyanDB 0.8(OAP 10.2 required) is easy, stable and production-ready. Don't need H2 as default storage anymore.
* [Breaking Change] Enhance JDBC storage through merging tables and managing day-based table rolling.
* [Breaking Change] Sharding-MySQL implementations and tests get removed due to we have the day-based rolling mechanism by default
- `./mvnw test ...` by its nature only runs unit tests, whose name is pattern of `*Test`, and it does never runs integration tests, whose name is patter of `IT*` or `*IT`, so in this PR we use `./mvnw clean test ...` to only run unit tests.
- `./mvnw integration-test ...` will run integration tests and unit tests, so we have `skipUTs` to control whether to skip the UT when running ITs, we already had this before.
- As for ITs, we have two groups, one is normal tests without any `@Tag`s, the other one is slow integration tests, which is annotated with `@Tag("slow")`, so we divided the integration tests into two workflow jobs:
- `./mvnw -DskipUTs=true clean integration-test -DexcludedGroups=slow ...` run the ITs but don't run the slow ITs and UTs, `-DexcludedGroups=slow` excludes tests annotated with `@Tag("slow")`
- `./mvnw -DskipUTs=true clean integration-test -Dcheckstyle.skip -Dtest=${{ matrix.test.class }}` run the slow ITs (because `excludedGroups` is not set) one case at a time, by setting `-Dtest={{ class }}`, not run UTs,
* Polish a log to doc and menu for latest status.
* Add a skip
* Add .github/actions/skip/action.yml itself to skip file
* Polish doc a little

Here are the basic and simple usages of the MeterSystem APIs.
## Meter Creation
New meter could be created based on metrics name, function, scope and data type.
1. Metrics name is still the storage entity name.
2. Functions are every similar with the OAL function, just accepting different input.
```java
final MeterSystem meterSystem = MeterSystem.meterSystem(getManager());
meterSystem.create("test_long_metrics", "avg", ScopeType.SERVICE, Long.class);
```
NOTICE, this creation should only be called in the `module#prepare` stage, otherwise, `Can't create new metrics anymore` exception will be raised after the **CORE** module `start` stage finished. You may find out, there is a chance `create` could be executed successfully in your own `module#start` stage, but it it just because of the sequence of provider loaded by the class loader, **no guarantee, so please don't do that**.
## Runtime Calculation
`AcceptableValue` is the object created at the runtime to accept new metrics value.
```java
final MeterSystem service = getManager().find(CoreModule.NAME).provider().getService(MeterSystem.class);
Executors.newSingleThreadScheduledExecutor().scheduleAtFixedRate(new Runnable() {
@Override
public void run() {
final AcceptableValue<Long> value = service.buildMetrics("test_long_metrics", Long.class);
value.accept(MeterEntity.newService("abc"), 5L);
value.setTimeBucket(TimeBucket.getMinuteTimeBucket(System.currentTimeMillis()));
service.doStreamingCalculation(value);
}
}, 2, 2, TimeUnit.SECONDS);
```
## Meter Functions
Right now, only `avg` function has been implemented. I submit this PR as soon as possible to get your feedback. I will add more functions.
## Notice
1. Make slow trace query available in the sampled record. Logically, they are the same thing. The UI doesn't need to concern about the trace as a special case.
2. Endpoint dependency will be removed from the dashboard. Because no query available for it. We will provide a new page for that in 8.1
3. Comparison page will be removed due to dashboard is powerful enough to replace it.
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
