Title:
  Neutron metadata agent can't handle high loads

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

Bug description:
  We've noticed that under high loads - 100's of VMs booting
  simultaneously from multiple tenants, that the metadata agent simply
  can't keep up, and the VMs fail to get their metadata.

  Debug showed that the listen backlog was being overflowed, but
  changing that manually only made things a little better.  It wasn't
  until multiple threads were started that the problem went away.

  Opening this bug to get these upstream since they help with the
  scalability of Neutron.

  1) Change the metadata-agent to support having multiple worker threads
  2) Change it to support a configurable listen backlog

  I'll assign this to myself and get the changes out for review.
