Dmitry Tantsur 13c6b6bdf1 Add element for hardware discovery ramdisk for ironic-discoverd
ironic-discoverd [1] is a StackForge project for conducting hardware properties
discovery via booting a special discovery ramdisk and interrogating hardware
from within it. It aims to be one of the official means of hardware properties
discovery for Ironic in Kilo release [2].

The ramdisk collects hardware information from the machine
it's booted on and posts it to the URL provided via
kernel argument 'discoverd_callback_url'.
