Use bulk-delete to delete multiple files
           from an account
            with a single request. Responds to DELETE requests with a
            header 'X-Bulk-Delete: true_value'. The body of the DELETE
            request is a new line-separated list of files to delete.
            The files listed must be URL encoded and in the
            form:
    /container_name/obj_name
    If all files are successfully deleted (or did not
        exist), the operation returns HTTPOk. If any
        files failed to delete, the operation returns
        HTTPBadGateway. In both cases, the response body
        is a JSON dictionary that shows the number of files that were
        successfully deleted or not found. The files that failed are
        listed.
