Add support for extra files. Recommend a subfolder be created and then referenced with the -x, --extra-file option for simplicity.

@steve-daedilus could you provide an example showing how to use the extra-files option? where do they end up? should I copy them back to /target using a late-command? I tried to add a directory and the files do not show up in the final iso.

The way I use this is to cd to the directory with the script in. Within that I have a "scripts" directory, and within that I have the files I want to include.

To include the files, I include the parameter line
-x scripts

The referenced folder "scripts" is copied recursively to the nocloud folder in the ISO.

I have a late-commands section in my user-data.yml to copy files to where they need to go on the deployment, such as:

cp /cdrom/nocloud/scripts/* /target/opt/
