nics is a great flexible parameter, but it's wordy. Shade now supports a simple parameter too, which is just "network" and takes a name or id. Add passthrough support. In addition to supporting booting from a pre-existing volume, nova and shade both support the concept of booting from volume based on an image. Pass the parameters through. Shade supports boot-time attachment of additional volumes for OpenStack instances. Pass through the parameter so that ansible users can also take advantage of this.
