Take the DHCP lease duration arg on the message to IpClient.

DHCP lease duration is also required when IpClient sends a RTM_NEWADDR
message to kernel to install an IPv4 address(preferred/valid params).
Put the lease duration as arg1 in the state machine message and IPv4
link address as object param.
