Pass device attributes into json uplink

[hallard]

Summary

Allow the device attributes (and may be device description) to be read when received uplink data

Why do we need this?

I put information on these attributes to be able to do action on receive packet, that’s the goal indeed. I don’t want to request API to get these on each uplink I’m receiving.

What is already there? What do you see now?

We already receive a lot of information about device but no attributes nor device description.

What is missing? What do you want to see?

Feature implemented :-)
