Subject: [PATCH] docs: add a note on how to auto restart caddy on crashes with
 systemd

It was decided in https://github.com/caddyserver/dist/pull/92 that the
best way to auto restart caddy is using a systemd override file and
this documents how to do that.

+Or, for example, if you'd like caddy to restart itself after 5s if it ever crashes unexpectedly:
+```systemd
+[Service]
+# Automatically restart caddy if it crashes except if the exit code was 1
+RestartPreventExitStatus=1
+Restart=on-failure
+RestartSec=5s
+```
+
 Then, save the file and exit the text editor, and restart the service for it to take effect:
 <pre><code class="cmd bash">sudo systemctl restart caddy</code></pre>
