Fix relay agent ip for indirect DHCPv4 packets

When only default server config is supplied
    The indirect traffic should be relayed to default server
When both default and indirect config is supplied
    The indirect traffic should be relayed to indirect server

When relay agent IP is not specified in either direct or indirect config
    For direct clients, use client interface IP as relay agent IP
    For indirect clients, keep original relay agent IP in the DHCP packet
