dhcp: add "ipv4.dhcp-client-id=duid" setting
Add a new mode for the DHCPv4 client identifier.
"duid" is what the internal (systemd) DHCP client already does by
default. It is also the same as used by systemd-networkd's
"ClientIdentifier=duid" setting. What we still lack (compared to
networkd) are a way to overwrite IAID and the DUID.
Previously, this mode was used by the internal DHCP plugin
by default. However, it could not be explicitly configured.
In general, our default values should also be explicitly selectable.
Now the "duid" client identifier can also be used with the "dhclient"
plugin.
