Add a new templates to configure radvd and dhcpv6 relay.
For IPv6 routed network the radvd daemon and the dhcpv6
relay is hosted on the same instance.
Since we do not want the networks in the OVB infra to
provide any DHCP or auto configuration we cannot use
neutron routers for provisioning network routing. The
instance running dhcpv6 relay and radvd will also be
the router for the provisioning networks.
Bump template version in undercloud-networks-routed.yaml
to version 2015-10-15. Need this version to avoid error:
'Items to join must be strings not
{u'str_split': [u'/', u'fd12:3456:789a:3::/64', 1]}'
