Urbit Harbor is a supervisor for Urbit ships on the local machine. It does no
orchestration, it just manages systemd services.

Plan:
    - make this run 10 fake galaxies
    - make this run 100 fake ships

- Requirements:
  - setup new ship

Setup process:

    <running as user "urbit-harbor">
    dir=/var/urbit/harbor
    urbit -c $dir/zod -k $dir/zod.key -x          # one-time setup
    <create $dir/zod.service from some template>
    systemctl --user enable $dir/zod.service      # nees fullpath
    systemctl --user start zod.service

Service Template:

    [Service]
    ExecStart=urbit -tq /var/urbit/harbor/zod  # maybe want -d?
    ExecStartPre=mkdir -p /var/urbit/harbor/zod

    [Unit]
    Description=zod

    [Install]
    WantedBy=multi-user.target

TODO:
    - use systemd.resource-control to limit memory/CPU for ships
      - Urbit.Cloud controller will set different limits by reading/editing the
      ini file, and change price to customer
    - figure out what firewall stuff i need to do
