Description

I found that we built the spamassassin container image everytime we run a test using this container.
It's testcontainer default behavior when a container image is built programmatically. However, it not only deletes the image but any cached layer, preventing reuse and thus speed gains.
By the way, as images share the same layers, not deleting the images has almost no space usage.
We should disable deleteOnExit option.
