    DVR: Increase the link-local address pair range
    
    The current dvr_fip_ns.py file has FIP_LL_SUBNET configured
    with a subnet prefixlen of /23 which only allows 255 pairs of
    link-local addresses to be generated. If the number of routers
    per-node increases beyond the 255 limit it raises an assertion.
    
    This patch increases the link-local address cidr to be a /18
    to allow for 8K routers. The new range was chosen to not
    overlap with the original, allowing for in-place upgrades
    without affecting existing routers.

  per node

Status in neutron:
  Fix Released

Bug description:
  The current 'link-local-address' allocator for DVR routers has a limit
  of 256 routers per node.

  This should be configurable and not just limited to 256 routers per
  node.
