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.

Generate interfaces file before cloud-init runs Cloud-init needs to query the metadata server after the network interfaces are configured. The upstart job "cloud-init-nonet" is specifically in place to provide a hook to block cloud-init from running while we rearrange network interface configurations.
