Title:
  prevent multiple neutron-netns-cleanup running simultaneously

Status in neutron:
  Invalid

Bug description:
  Debian Neutron has set a cron entry to invoke neutron-netns-cleanup
  every hour, in ordinary system, it works fine, but in our heavy stress
  test environment, I found there are over 10 neutron-netns-cleanup
  processes running.

  Can we introduce a lock which can prevent spawning new instance when
  there is already one running ?
