conf_replace

You can add the conf_add plugin similar to the conf_replace plugin, but instead of replacing grub.cfg/isolinux.cfg it adds the code to grub.cfg/isolinux.cfg.

conf_add will break the directory metadata of ISO file. 
It's not in the same difficulty level as conf_replace and IMHO it's rarely used.

conf_add 应该可以通过基于 conf_replace 的方法实现：把 ISO 内的配置文件内容读过来，加上用户定义的内容，再利用 conf_replace 把生成的配置替换进去。

这个相当于是 conf_append，我感觉没太大必要，用户自己在新的文件里面内包含原来的配置文件内容就可以了。
conf_replace 基本的使用场景就是这种，新的配置文件一般不会重新写，都是在原来的基础上修改或者增加配置。
