[feature] Add API endpoint that returns co-ordinates on indoor map (floorplan)

[pandafy]

Add an API endpoint that takes the location ID and returns co-ordinates of all the devices.

• It should also return all available floors in the location.
• It should be possible to filter the devices based on the floor.
