Adds a pxe deploy driver to support the concept of a deployment just consisting of a ramdisk. Ideally, as long as a kernel and ramdisk are defined, either by the operator or via a glance image, the PXE/iPXE template should point the booted kernel to using ramdisk as the root. In theory, this would allow deployment via nova, or directly using the parameters posted to the node's instance_info. There may be additional features realistically needed for this to be beyond minimally useful, but that would also depend on the contents of the ramdisk that is deployed by an API user.
