dhcpv6-pd: T2821: support dhcpv6-pd without "address dhcpv6"
Currently DHCPv6-PD requires an interface address configured to dhcpv6 on the
CLI. This is not required also sometimes there is either no dhcpv6 interface
addressing available (PPPoE) or wanted. This limitation was artificial due to
the old interface code.
Change the implementation to spawn the DHCPv6 client and request a prefix even
when there is no address request configured.
