Prometheus metrics

[wociscz]

Not an issue!
Just an idea: It'd be nice, if we already running webserver for ui, to expose /metrics path with prometheus metrics. Same information as Status page gives but in plain prometheus text format. In bytes, no other math around. Just the things which wg show all dump gives us.
Maybe labeled values with at least name would be even more perfect, so then we can have graphs in graphana, for example.

@ngoduykhanh I also have a use for this feature and would be willing to open a PR and implement it if you are ok with the idea and want it adding to the project? Basically just want to get your opinion before I start working on it.

It could be performed outside the wireguard_ui with help of https://github.com/kbknapp/wireguard_exporter (and maybe others), without the labels (naming) of course.
