Remove left over docker images

[KyleAure]

As a user of the system-test package, I would like to use the integration test capabilities of this package for test driven development. However, after performing an integration test, there is an un-tagged docker image left over (in this case liberty). These images should be cleaned up after tests are done.

kyleaure $  docker images

I assume you are using the default new MicroProfileApplication() constructor here? If so, this should resolve using new ImageFromDockerfile(String dockerImage), which does delegate to ImageFromDockerfile(String dockerImageName, boolean deleteOnExit) with deleteOnExit=true.

The images should be getting cleaned up automatically by Testcontainers with the JVM shutdown hook they register, but I can see locally that's not happening for some reason.

Should be fixed by testcontainers/testcontainers-java#1745

@KyleAure is this one still relevant?
