some ideas

hi, i am the author of device-opcua-go and i'd like to share some of my views.

I noticed you guys have put NodeId and Monitor info into deviceResources' artibution in DeviceProfile(DP), so here they are:

1. A DP can be thought of as a template of a type or classification of Device. Different devices may have different NodeId, thus DP shouldn't contains any of spec nodeid, shoule it? I suggest you can put these info into [DeviceList.Protocols.OPC-UA] of configuration.toml file.
2. " monitored: "True" " means you can monit this item but if user wants to stop or restart monitor, they need to delete, modifiy and re-update DP, which is very complex so i think it shouldn't be written into DP nor be same with all device.
3. Add subscribe function as a command to DP. As a result, user can use it at their needs just like other commands.

I've been doing these works in device-opcua-go recently. I'll attach my code when it is done!

Hope my ideas can be taken into your considerations!
