title: Set OSM config options using API and not the global config file
body: <p>When reading OSM files using GDAL, the fields that are read are defined in <code>osmconf.ini</code>, and if I want that certain tags don't appear within the <code>other_tags</code> then I need to add them to the <code>attributes</code> value in the corresponding sections.</p>
  
  <p>This works fine, but is not really portable, so my questions is, is there a ways to define the settings saved in <code>osmconf.ini</code> in a portable way per project?</p>
