Title:
  NVP metadata access must require overlapping IPs

Status in OpenStack Quantum (virtual network service):
  Fix Released

Bug description:
  In order for the metadata access network to work, overlapping IPs must
  be enabled in Quantum.

  Otherwise the creation of the metadata access network will fail when
  more than one router is configured as there will be an overlap on
  169.254.169.252/30

  Note: we could partition the link-local address space enabling up to
  8192 routers to work with non overlapping IPs, but this is probably a
  complication that we would prefer to avoid, at least for the grizlly
  release (especially as overlapping ips should be the 'default'
  options).

  The fix for this bug should prevent metadata access network from being
  configured on the NVP plugin if allow_overlapping_ips=False
