This initial commit defines several modules for ingesting from JDBC and specifically from PostgreSQL and MySQL. The two latter modules define separate unit tests and integration tests, and prior to running the integration tests create a Docker image with the respective database and start a Docker container. Any *.sql or *.sh files are run on database, allowing the modules to easily create and populate databases used in the tests. The integration tests are then run (using the failsafe maven plugin), and regardless of whether there are any failures the Docker container is always shutdown (at least when running `mvn install`). See the modules' README files for details.
