Revert "Merge branch '1769_drop_support_gdal_1' into 'develop'"

Merge request !334 (merged) has been merged to fast. There is a failing build (https://dash.orfeo-toolbox.org/viewBuildError.php?buildid=348519), and a discussion has been reopened (!334 (comment 75233)). Therefore we need to revert the changes merged in develop.
