Run all integration tests using a MySQL test container instead of HSQL

Replace HSQL with MySQL for higher fidelity integration tests and to
be able to also test native queries and platform-specific functionality.

+### Testcontainers
+By default, if no datasource is configured in the application.properties file, integration tests rely on 
+[Testcontainers](https://www.testcontainers.org/)
+to 
+provide a configured
+MySql instance in a test-scoped container.
+
+For that to work,  you will need Docker installed and running on the local machine. 
+
+See [general Docker requirements](https://www.testcontainers.org/supported_docker_environment/) for Testcontainers.
+
+### Test command
 ```sh
 cd ${PROJECT_DIR}
 mvn test
