Add integration test workflow

Add an `integration-test.yaml` workflow that starts all the available tests for a given Log4j version.

This workflow is started:

- at each modification of this repository.
- once a day to test the latest Log4j snapshot.
- manually, after we close a Staging Maven Repository during the release process.
