The version extraction assumed that the version is everything after the
last `-` in the container name. This doesn't work if you deploy a
non-MRSK generated version that contains a `-`.
To fix we'll generate the non version prefix and strip it off. In some
places for this to work we need to make sure to pass the role through.
