Init urbit harbor

This is mostly stubbed out and needs some work to be functional... the idea is
to run urbit ships as systemd services, and provide a simple interface for
managing them.

+
+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
