Tutor-minio: setting MINIO_DOMAIN

Is there a way to set MINIO_DOMAIN (equal to LMS_HOST standard) in tutor-minio plugin?
This is needed so minio can figure out the bucket name from a presigned url !

Update: @regis, please see my pull request in tutor-minio - Solved with this uploading of video (using the old boto based code there) from Studio !!
