[FEAT] Improve observability capabilities within the container

[proffalken]

Is this a new feature request?

• I have searched the existing issues

Wanted change

It would be great to be able to somehow expose metrics about number of clients connected, data throughput etc. from the Wireguard server and pull that information into Prometheus

Reason for change

Observability is key in many organisations, adding this feature to the docker container will make it even more appealing in my view to other users.

Proposed code change

No response

Wireguard does not provide any kind of metrics endpoint that can be queried to obtain that kind of information and as it is stateless, the concept of a "connected" user doesn't really exist, just a user who has sent traffic in the last X timeframe.

Ah, ok, I'd got confused by the availability of https://github.com/MindFlavor/prometheus_wireguard_exporter, but having re-read those docs I see now that it just runs commands against wg and reports back what it finds.

I'll close this, thanks.
