Please provide a /system/routerboard datasource

Is your feature request related to a problem? Please describe.
The new firmware of mikrotik changed something with sfp's. It is important to upgrade the "current firmware" of a routerboard system.
It took two days to figure out why a switch had some issues, while others are working fine.
I forgot to add the routeros_system_routerboard_settings auto-upgrade=true terraform resource.
In the output of a terraform run, I output the "upgrade-firmware", architect and modelnr of every switch.
If I had a way to report the /system/routerboard properties, I had noticed it directly.

Describe the solution you'd like
Have a datasource about /system/routerboard
