Add ingest routine

[scottsfarley93]

All data ingestion is currently done manually.

Add a data ingestion routine that could operate via a post request on the API. Only authenticated users should post data, so this would require the addition of a user authentication method.

The program could look like this:

1. Check that a netcdf was uploaded with the request.
2. Get band interpretations, source, and variable from the api post data json
3. Use NetCDF4 python bindings and gdal python bindings to extract the netcdf to a numpy array and then to a gdal raster
4. Use gdal_merge to combine bands
5. Execute standard ingest procedures to add database table and records in the database.
