Describe this PR

• I refactored the submission download endpoint to be a single endpoint, with option csv, json, or geojson.
• When downloading geojson, I also extract the additional geometry fields (that should always end in _geom as a Feature in the final FeatureCollection).
• The extra feature is like this:

{"type": "Feature", "id": "65bfe40a-df0f-4f51-9257-e341c9515b87", "geometry": {"type": "Point", "coordinates": [85.302801, 27.712952]}, "properties": {"is_additional_geom": true, "id_field": "kathmandu_point_extract", "geom_field": "kathmandu_point_extract_geom"}}]}

• As you can see:
  • The "id" field is the entity id.
  • The "is_additional_geom": true property is set.
  • The "id_field" property is set to the submission json field that contained the ID (where the entity list name is also kathmandu_point_extract in this case.
  • The "geom_field" property is set to the submission json field that contained the geometry (javarosa string).

Review Guide

• Create a new submission for a project with additional datasets.
• Select the additional entity during submission.
• Extract a submission geojson and display in QGIS (it will likely have mixed geom: Polygon + Point).

Mistakenly merged it to development. Sujan and I reviewed the code, and it looked good.
