Add an advanced hardware discovery plugin based on eDeploy

Get the thousand facts detected by an eDeploy hardware detection and extract the needed information in an ironic-discoverd plugin.

The plugin will receive the hardware information on the key 'data' into the node_info from the ramdisk. The info is a list of tuples with 4 elements reported by the hardware module https://github.com/enovance/hardware . The extracted information will be matched by the configured hardware profiles. The variables from the matched profile will be added into the 'hardware' key in node_info.
