Add IPv6 support for _move_neutron_addresses_route

Browse Source 
Added functionallity to allow IPv6 addresses to be moved to the
OVS_PHYSICAL_BRIDGE from PUBLIC_INTERFACE automatically using
_move_neutron_addresses_route. Only PUBLIC_INTERFACE and
OVS_PHYSICAL_BRIDGE need to be set in localrc.

HOST_IP must be set in localrc. HOST_IPV6 must be set in localrc if a
global IPv6 address is configured on PUBLIC_INTERFACE.
