Static/Monitoring rewrite

[genofire]

For me a short remindert, i am a main developer of the more or less well supported monitoring tool yanic.

After the time, i have seen a lot of code supposed to monitoring in a mesh network, which all are very small single point of code usage.
In the world of cloud, i see that the tools become more easier and standarize e.g. Prometheus.

So i have this Idea / Suggestion for an easy monitoring setup:

• respondd only announce nodeinfo (so an monitoring-solution could discovery nodes)
• the gluon "status-page" get an permanent metric endpoint (ala https://openmetrics.io/ / Prometheus)
  • that could be used by the status page, Prometheus of course, but also other systems like influxdb
  • the metrics names could be like the openWRT package prometheus-node-exporter-lua and/or official prometheus node-exporter + new metrics for links between nodes

I believe that would create more synergy between normal hosting/monitoring and freifunk/gluon.
