 * Run maven in a docker container.

 *   For example, when running integration tests, unit tests that use infrastructure that binds to ports or
 * * when one maven repo per builds is required
 *   For example when concurrent builds of multi module project install the same snapshot versions.
 *
 * The build are run inside the official maven containers from https://hub.docker.com/_/maven/
