Public bug reported:

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
