      Description

      When you create a file with overwrite=true, you don't care that a path resolves to a file, only that there isn't a directory at the destination.

      S3A can use this, bypass the GET path and only do a GET path + "/" and LIST path. That way: one HTTPS request saved, and no negative caching of the path to confuse followup checks.

      That is: better performance and consistency
