This patch creates or updates the symlink "latest_iso_build" in the
archive and publish areas, immediately after the ISO build succeeds, but
before the other stages (docker images etc).
This allows external users to reference that path to download the latest
ISO, even if the overall build had failed due to docker image build
errors.
TESTS
================================================
Run a build where on of the docker images fails to compile
Make sure the new ISO build symlink gets created, even though the
overall build fails.
