What's and how exported

Example of all metrics related to syncthing here.

For data obtaining is using five endpoints:

GET /rest/svc/report
GET /rest/system/connections
GET /rest/stats/device
GET /rest/db/status*
GET /rest/config/devices

* This is an expensive call, increasing CPU and RAM usage on the device. Use sparingly.
