This patch is reducing the size of the ramdisk image generated by the ironic-agent element. It does remove extra packages (graphical stuff, dev stuff, miscs, docs, etc...) and purges directories that are not needed for a ramdisk (like /boot since it boots using an external kernel) Currently it was tested generating a Fedora 22 image and reduced the size of the final image from 464 MB to 211MB compacted (54% decrease). I was able to boot a VM with 1.3 GiB of ram instead of the previous 3 GiB needed. Change-Id: Id6333ca5d99716ccad75ea1964896acf371fa72a
