I would like to use wireproxy with kubernetes, but for the http proxy, I'm missing a health endpoint:

/livez:

• 200 if tunnel is established (e.g. no config error, unresolvable dns, etc.)
• 503 otherwise

/readyz:

• 200 if latest keepalive received
• 503 otherwise

This will use wireguard config PersistentKeepalive for period.
Kubernetes can use failureThreshold to ignore intermittent failures.
