Do not rely on gdalinfo subprocess calls nor gdal_bin

[francois-baptiste]

It would be best if we can rely only on python wrapped gdal (like rasterio) instead of relying on subprocess calls

In the google clound shell I got the following error

fbaptiste@cloudshell:~/raster-loader (cartodb-on-gcp-datascience)$ carto bigquery upload --file_path ./raster_loader/tests/fixtures/mosaic.tif --project cartodb-on-gcp-datascience --dataset fbaptiste

running sudo apt-get install gdal-bin fixed the problem but a full python managed solution would be best as you have to rerun this install at every start up on google cloud shell
