+ allow to set log_format (switch order of log_file with http options

[maqdev]

Setting http options before access_log/error_log give ability to define log format like this:

    nginx_access_log: /var/log/nginx/access.log main
    nginx_http_options:
      - |
        log_format main '$http_x_forwarded_for - $remote_user [$time_local] "$host" "$request" ' 
            '$status $body_bytes_sent "$http_referer" '
            '"$http_user_agent" $request_time';
