    Deletes all objects in the container.

    By default, this will perform one pass at deleting all objects in
    the container; so if objects revert to previous versions or if new
    objects otherwise arise during the process, the container may not be
    empty once done.

    Set `until_empty` to True if you want multiple passes to keep trying
    to fully empty the container. Note until_empty=True could run
    forever if something else is making new objects faster than they're
    being deleted.

    See :py:mod:`swiftly.cli.delete` for context usage information.

    See :py:class:`CLIDelete` for more information.
