Build cloud native images on tags

When on a tag, trigger a multi-project pipeline in the CNG repostiory. Opting for a trigger rather than an addition to our release-tools project for a few reasons: - The Dockerfiles in the CNG image repo change infrequently, and as a result I don't feel the need/overhead for stable branches in that repo at this time - My intent with the CNG repo, is that once stable, the Dockerfiles would actualy move to their component projects, to be versioned with the code they are building - It is likely that we will want to followup with a manually triggered package for branches for devs, and possibly review apps, so it made sense to build the CNG ci jobs to accept this sort of pipeline.
