Title:
  Nova Docker driver doesn't remove created network namespace

Status in OpenStack Compute (Nova):
  Fix Released

Bug description:
  The Nova Docker driver doesn't remove the network namespace after
  machine has been destroyed.

  Steps to reproduce:

  1. Look up available network namespaces, on a fresh machine the list should be empty:
      $ ip netns show


  2. Start a new docker container via nova
      $ nova boot --image busybox:latest test1

  3. Look up available network namespaces:
      $ ip netns show
      5f6b61d44ae15a77b277ebbf422fe88f369f8cdbb81a64aa6ea4beaf110204a6

  4. Destroy nova instance
      $ nova delete test1

  
  5. Look up available network namespaces, the list must be empty but isn't
      $ ip netns show
      5f6b61d44ae15a77b277ebbf422fe88f369f8cdbb81a64aa6ea4beaf110204a6

  
  The nova drive must remove this network namespaces on instance destroy by calling: 

      ip netns delete $container_id
