    DHCP agent: advertise SLAAC prefixes
    
    Advertise IPv6 SLAAC prefixes via router advertisements with router
    lifetime of zero so prefix can be discovered on isolated networks.
    Since the router lifetime of these RAs is zero, they will not be used as
    a next hop. Implementing this now so Octavia can use an isolated IPv6
    network.

Title:
  [RFE] DHCP agent should provide ipv6 RAs for isolated networks with
  ipv6 subnets

Status in neutron:
  Fix Released

Bug description:
  Currently, if there is no router attached to a subnet, then instances
  cannot walk thru IPv6 address assignment because there is nothing on
  the network that multicasts RAs that would provide basic info about
  how ipv6 addressing is handled there. We can have DHCP agent to run
  radvd in that case. Then instances would be able to receive IPv6
  addresses on isolated networks too.

  We could try to rely on https://tools.ietf.org/html/rfc4191.
