[Feature request]: Ability to set the room to be ingested into Home-Assistant directly in Z2M

[samip5]

Is your feature request related to a problem? Please describe

I'm annoyed that I cannot currently set the area/room the device is in, so that it would go to it's right place in Home-Assistant directly

Describe the solution you'd like

I would like a way to tell Home-Assistant in MQTT discovery in which room/area it should be placed into.

Describe alternatives you've considered

N/A

Additional context

I'm not sure if Home-Assistant supports this yet, but it would be useful.
