Jens Rosenboom ccebded0cb Update network metadata type field for IPv6
Currently it is not possible to decide from looking at the network
metadata whether an IPv6 subnet is using slaac, dhcpv6-stateless or
dhcpv6-stateful.

So we add ipv6_address_mode information into the subnet metadata when
it is available and use that to construct the subnet type.

As a result, the type for a subnet with mode SLAAC will be "ipv6_slaac"
instead of "ipv6_dhcp" and similarly for the other available modes.

features:
- |
The network.json metadata format has been amended for IPv6 networks
under Neutron control. The type that is shown has been changed
from being always set to ``ipv6_dhcp`` to correctly reflecting the
``ipv6_address_mode`` option in Neutron, so the type now will be
``ipv6_slaac``, ``ipv6_dhcpv6-stateless`` or ``ipv6_dhcpv6-stateful``.
upgrade:
- |
The information in the network.json metadata has been amended,
for IPv6 networks under Neutron control, the ``type`` field has been
changed from being always set to ``ipv6_dhcp`` to correctly reflecting
the ``ipv6_address_mode`` option in Neutron.
