p2k16-label: the service needs a proper home, and needs to be in our ansible setup

[tingox]

the p2k16-label service currently lives on the server heim, in Elias' home directory. It has a systemd service (label-writer.service), but everything is manually installed. This breaks when we do upgrades. Today I fixed it by manually installing

sudo apt install python3-pil
sudo apt install python3-qrcode
sudo apt install python3-paho-mqtt
sudo pip3 install brother_ql

and restarting the label-writer.service.

Needs fixing:

• make a proper home for it (on heim, under a dedicated user? Or somewhere else?)
• create an ansible role for it
• make sure that all dependencies gets installed

Also, we might need to find a replacement for brother_ql:

ed in a future release
