When dhcp configuration is attempted add the network interface to a
'dhcp' group . Present 'dhcp' as the default value for the ip address
of interfaces in the 'dhcp' group, not the address the previous dhcp
configuration might have obtained. Makes it 'safer' to restart
installs after network configuration.
