 * Mojo for removing images. By default only data images are removed. Data images are
 * images without a run configuration.
 *
 * By setting removeAll (property: docker.removeAll) also other
 * images can be removed.
 *
 * In order to explicitly restrict the images to remove, use images to specify a
 * (comma separated) list of images to remove.
