Subject: [PATCH] transplant: Generate extra interfaces config file
The DEA override may contain a IFCGF_<interface> section in its 'fuel:'
section, containing the necessary keys to produce a ifcfg-<interface>
file, like in this example:
fuel:
IFCFG_ETH1:
device: eth1
ipaddress: 10.0.1.10
netmask: 255.255.255.0
gateway: 10.0.1.254
FIXME: In order for Network Manager to use the newly added interfaces
for outgoing traffic and honor their GATEWAY setting (e.g. if we just
added one public interface), the default route on admin iface (most of
the time called eth0) should be disabled. For now, we assume the admin
interface is always "eth0".
