MEDIUMTEXT in H2 is CLOB in JDBC type, and casting it to `String` causes `ClassCastException`

- Add length definition with reasonable default value.
- #content of @Column has been renamed to storageOnly . I add this to many fields as they are not being query in any case.
- Merge H2 and MySQL columntype mapping back to consistent.
- Remove @IDColumn.
- Support @QueryUnifiedIndex.
- Refactor the MySQL and H2 installers to use @Column and @QueryUnifiedIndex definitions to create indices automatically. But the index naming rule has been changed to entityseqIDX. seq is the Increment Interger for every entity.
- Support @MetricsExtension and insertOnly in the MetricsPersistentWorker worker.
- Optimize MetricsStreamProcessor

Motivation:

According the feedback from the community, the e2e tests are hard for
them to understand and get them started, so this pull request aims to
rewrite the e2e tests with some improvements:

- debuggable locally, now you can run every individual case directly
inside the IDE, just like running a plain unit test.

- same functionalities of multiple counterparts share the same codes,
cases like different storages and cluster coordinators share the same
codes, easy to add more similar cases.

- the "end" now extends to the Doccker images, meaning that some bugs
like #4483 and #4471 can be more easily and early to be discovered.

- codes style and license headers are checked

Modifications:

- adopt jupeter (a.k.a junit 5), testcontainers as the new test
framework, all containers are orchestrated by docker-compose.yml,
well-known technology that developers should be familiar with.

- rewrite all test cases and verify them.

- reorganize the workflows in GitHub Actions.

Result:

- new e2e test should be easy to add.

- closes https://github.com/apache/skywalking/issues/4472
