    tests: don't allow oslo.config to autodiscover config files

    oslo.config makes attempts to autodiscover configuration files using
    find_config_files() helper. If e.g. /etc/neutron/neutron.conf exists,
    and is not readable, the following test failure can be experienced:

    oslo_config.cfg.ConfigFilesPermissionDeniedError: Failed to open some
    config files: /etc/neutron/neutron.conf

    Unit tests must not rely on any external state of the system and run
    successfully no matter whether neutron is actually installed on the
    system, or not.
