Bug description:

  Release: Grizzly

  Sometime when creating instances, the dnsmasq instance associated with
  the tenant l2 network does not have configuration for the requesting
  mac address:

  Restarting the quantum-dhcp-agent resolved the issue:

  Jun 11 09:30:41 d7m88-cofgod dnsmasq-dhcp[11060]: DHCPDISCOVER(tap98031044-d8) fa:16:3e:da:41:45
  Jun 11 09:30:41 d7m88-cofgod dnsmasq-dhcp[11060]: DHCPOFFER(tap98031044-d8) 10.5.0.2 fa:16:3e:da:41:45

  The IP address (10.5.0.2) was re-cycled from an instance that was
  destroyed just prior to creation of this one.
