    Trigger dhcp port_update for new auto_address subnets
    
    When an ipv6 auto_address subnet is added to an existing network with IPv4
    subnet, the dhcp port in the network is simply updated with an IPv6 address.
    However, neutron does not send any port_update notification for the dhcp
    port. This causes inconsistencies (while configuring anti-spoofing rules)
    for external controllers (like OpenDaylight) as the dhcp port info
    in controller does not match with the dhcp port info in Neutron db.
    This patch addressess this issue by having the plugin send a port_update
    call when the dhcp port is updated with IPv6 auto address.
