As per a thread on the mailing list [1], this issue was already fixed
[2] in Neutron in Juno and backported to Icehouse, so I'm going to
remove Neutron as an affected project.

Bug description:
  A change was made to the neutron portion of the nova metadata service
  to disable caching.  This ends up causing a all hits to the nova
  metadata service to generate messages to retrieve data from neutron.
  Doing so makes a "crawl" of the metadata service take at least 8x
  longer than it did.  cloud-init crawls the metadata service during
  boot.  The end result is that instances boot significantly slower than
  they did previously.
