Title: dhcpv4: implement router configuration option

RFC 2132 defines:

3.5. Router Option

The router option specifies a list of IP addresses for routers on the
client's subnet. Routers SHOULD be listed in order of preference.

The code for the router option is 3. The minimum length for the
router option is 4 octets, and the length MUST always be a multiple
of 4.

Code Len Address 1 Address 2
