Switch MMW Front-End to Use Geoprocessing API for Mapshed, GWLF-E

[rajadain]

Once #3472 and #3473 are in:

• Switch the front-end to use the new public endpoints
• Ensure that the modeling works correctly for anonymous and logged in users
• Remove the old internal endpoints
• Update any tests (consider moving them to the geoprocessing_api app if needed)

Need to move these endpoints to the public API under subbasin as well:

model-my-watershed/src/mmw/apps/modeling/views.py

	@decorators.api_view(['GET'])
	@decorators.permission_classes((AllowAny, ))
	def subbasins_detail(request):
	mapshed_job_uuid = request.query_params.get('mapshed_job_uuid')
	mapshed_job = Job.objects.get(uuid=mapshed_job_uuid)
	gmss = json.loads(mapshed_job.result)
	if gmss:
	huc12s = get_huc12s(gmss.keys())
	return Response(huc12s)

	catchment_comids = json.loads(unquote(encoded_comids))
	if catchment_comids and len(catchment_comids) > 0:
	catchments = get_catchments(catchment_comids)
	return Response(catchments)
	else:
	return Response(status=status.HTTP_404_NOT_FOUND)

and to switch the front-end to use the new APIs.
