Query Prometheus metrics instead of running commands on hosts

[raspbeguy]

Hello, I was thinking that adding a Prometheus mode (query a Prometheus database that scrapes node exporter metrics) would have multiple advantages over direct hosts querying:

• A single endpoint connection (Prometheus URL) to handle for all monitored hosts, possibly consuming less battery
• No need for ssh access, so better security
• Possibility of automatically adding hosts, or filtering using Prometheus labels
