Gregory Haynes 6bdb810f38 Handle unconfigured interfaces for dhcp-all-ifaces 
On ubuntu, if an interface exists but is unconfigured then ifquery
$iface will return 0 but no output. This will cause dhcp-all-interfaces
to not attempt to dhcp on that interface.

===================
dhcp-all-interfaces
===================
Autodetect network interfaces during boot and configure them for DHCP

The rationale for this is that we are likely to require multiple
network interfaces for use cases such as baremetal and there is no way
to know ahead of time which one is which, so we will simply run a
DHCP client on all interfaces with real MAC addresses (except lo) that
are visible on the first boot.

The script /usr/local/sbin/dhcp-all-interfaces.sh will be called
early in each boot and will scan available network interfaces and
ensure they are configured properly before networking services are started.
