We have the following traceback in a networking-bgpvpn test [1].

    Guard against config_dirs not defined on ConfigOpts

    Turned out that if the code extracts config_dirs value from ConfigOpts
    objects before config files are parsed, then oslo.config will raise
    NoSuchOptError exception.

    This is not a usual mode of operation for the code, since main()
    function of the process using it is expected to parse CLI and config
    files before using it, it may nevertheless happen in some test code.

    This patch guards against those exceptions, falling back to
    /etc/neutron, as we already do when --config-dir is not specified.

    Closes-Bug: #1587359
