This patch adds support for a new kind of Glance image, a specially crafted ISO which supports iPXE booting, giving customers a means to roll their own image. Two virt-layer modifications were needed. The first was adding configurations for the iPXE ISO feature (network to use, boot menu, mkisofs_cmd). The second was the ability to inject networking info into the ISO after it was downloaded. To use this feature, operators should enable the `ipxe_boot` image-property.
