Waldemar Znoinski 4b222b8263 fix systemd resource deadlock 
Dependency to start network-pre (which
depends on network.target) before
dhcp-interface@.service collides with
Ubuntu's own network.target that suupose
to start after network-pre.

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.

On non-Gentoo based distributions 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.

On Gentoo based distributions we will install the dhcpcd package and ensure the service starts at boot. This service automatically sets up all interfaces found via dhcp and/or dhcpv6 (or SLAAC).
