this still has a long way to go, but it's getting there. Some stuff is not done properly at all

modifies the kvm recipe to take packer specific parameters, this is done so the json file packer relies on can be generated at runtime

as the recipe is pulled from git, we need to keep it up to date

a lot of the work done here is just duplicated from KVM's recipe. This is bad but works for now

 Those signatures are old and unused anymore.
