If you are deploying more than one destination to a host, the latest tags will conflict, so we'll append the destination to the tag. The latest tag is used when booting the app or exec-ing a new container. If a deploy doesn't complete on a host for all roles then we should probably not be using it, so move the tagging to the end of the boot process.
