Chris Jones a6b794fffc Add element to run DHCP on all network interfaces. 
Ensures that all network interfaces are present in
/etc/network/interfaces. Any interface not already defined there
will be added and configured for DHCP.

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 (except lo) that are visible on the first boot.

The script /usr/local/sbin/generate-interfaces-file.sh will be called early in each boot and will scan available network interfaces and ensure they are all present in /etc/network/interfaces.

Note that this element is only expected to be useful on Debian-derived distributions, currently.
