Title:
  Remove extraneous trace in linux/dhcp.py

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

Bug description:
  The debug tracepoint in Dnsmasq._output_hosts_file is extraneous and
  causes unnecessary performance overhead due to string formating when
  creating lots (> 1000) ports at one time.

  The trace point is unnecessary since the data is being written to disk
  and the file can be examined in a worst case scenario. The added
  performance overhead is an order of magnitude in difference (~.5
  seconds versus ~.05 seconds at 1500 ports).
