Support ephemeral keys / tailscale logout

[uthark]

If golink is deployed as kubernetes, pod, then each time pod is rescheduled, golink register it self as go-%d and so on.

Per tailscale documentation, I could use ephemeral keys, then device is automatically removed within 48h. Also, per docs one could use tailscale logout to force removal of the service from tailscale.

It would be nice, if golink would capture SIGTERM and do proper logout in tailscale.

If you have any good workarounds, please share.

@uthark, if golink is running as an ephemeral node, it should clean up after itself when shutting down. So the actual problem is that golink isn’t handling SIGINT and SIGTERM, like a good Unix daemon. This is probably as simple as using signal.NotifyContext.
