WIP: Implements the basic structure for the units list/map

- Updates the Devices and Positions APIs to properly construct the Url's query when there are null values
- Adds a units controller to the shared module
- Adds a devices and map fragment that each print the fetched units on the console
- Adds a units view model to connect previously mentioned fragments with the units controller
