Not output is given. We need to add at least the stats into stdout.

    Get rid of unused env variable

    TEMPEST_LOG_CONFIG was never interpreted within tempest.
    As a result logging.conf was only interpreted if log_config_append
    in tempest.conf was set manually.

    Logging properties are important for tempest CLI to ensure
    the user sees some output.
