                - "/var/log/cloud-final.err"

    Mode can be one of the configuration stages. If you pass a
    non-existent mode, it will assume the "all" mode configuration if
    defined.

    Stderr can be specified as &1 to indicate that it should
    be the same as stdout.

    If a file is specified with no redirection, it will default to
    appending to the file.

    If not overridden, output is provided in
    '/etc/cloud/config/cloud.cfg.d/05_logging.cfg' and defaults to:
        {"all": "| tee -a /var/log/cloud-init-output.log"}

    :param cfg: The base configuration that may or may not contain the
        'output' configuration dictionary
    :param mode: The mode to get the output configuration for.
    :return: A list of two strings (or Nones), the first for stdout for the
        specified mode and the second for stderr.
