This is progress! There are a few comments I'd like to make here, and I can be corrected if need be.

1. There are a couple of calls to systemctl daemon-reload and systemctl restart. We could squash these into one set of calls at the end. But that can be for a second draft
2. All of the source files that have .j2 exts are templates that can't just be copied over. These will have to be translated to consul template files, and they will be installed in /etc/consul-template/templates
3. I don't know if sudo is required for scripts within a package, since I think that all package commands are executed with escalated permissions anyway
4. If there is any metadata that we need to store on disk (say, the ansible variables), we can add them to /etc/mantl as files. We should keep that in mind as we build out the packages
