Expose more metrics? (All metrics?)

[C-Duv]

Issue type: Feature request

I would like to measure more metrics about system, DSL and bandwith usage:

• uptime (boottime in node_exporter)
• link, Internet and phone status ("connected" or "disconnected")
• DSL protocol (ADSL, VDSL, etc.)
• last sync DSL timestamp
• cumulative network traffic counter (node_network_receive_bytes and node_network_transmit_bytes in node_exporter)
• The whole "Stats xDSL" tab of Freebox OS's "État de la Freebox" app.
• Hard disk infos? (disk name, total space, used space)

Are you open to PR for theses metrics (disclaimer: I didn't checked if they were available via Freebox's API but I guess so because someapps have them...)

I've found this other exporter: trazfr/freebox-exporter which seems abandoned but exposed more metrics (by looking at its get_metrics.go source file).

(PS: Of course, thank you for this exporter)

Of course I'm open for PR, so don't hesitate!
