The IPv6 addressing mode is now configurable for the undercloud
provisioning network. The option ``ipv6_address_mode`` (default:
``dhpcv6-stateless``) in undercloud.conf is used to control the addressing
mode. Possible values:
- **dhpcv6-stateless**: Address configuration using RA and optional
information using DHCPv6.
- **dhcpv6-stateful**: Address configuration and optional information
using DHCPv6.
