net: handle openstack dhcpv6-stateless configuration
Openstack subnets can be configured to use SLAAC by setting
ipv6_address_mode=dhcpv6-stateless. When this is the case
the sysconfig interface configuration should use
IPV6_AUTOCONF=yes and not set DHCPV6C=yes.
This change sets the subnets type property to the full
network['type'] from openstack metadata.
cloudinit/net/sysconfig.py and cloudinit/net/eni.py
are updated to support new subnet types:
- 'ipv6_dhcpv6-stateless' => IPV6_AUTOCONF=yes
- 'ipv6_dhcpv6-stateful' => DHCPV6C=yes
Type 'dhcp6' in sysconfig is kept for backward compatibility
with any implementations that set subnet_type == 'dhcp6'.
