Create Mapping endpoints

[21chanas3]

We need some endpoints to communicate with the mapping module, mainly to receive the KML files. The mapping module should be able to receive all other required information from the other existing endpoints

The Vision subgroup will call the GroundObject endpoints to input sources of fire and hotspots that they find. We need an endpoint that collects all of these and places them into a KML file. The KML generation should happen off the main Django thread to keep the backend responsive, investigate using a Celery worker
