Title:
  Neutron is not compatible with iproute2 > v4.0.0

Status in neutron:
  New

Bug description:
  Starting with v4.0.0, iproute2 added 'set/get' commands to assign an id, also modifies 
  the 'list' command to make it show the id if an id is assigned.

      ipnetns: allow to get and set netns ids

      The kernel now provides ids for peer netns. This patch implements a new command
      'set' to assign an id.
      When netns are listed, if an id is assigned, it is now displayed.

      Example:
       $ ip netns add foo
       $ ip netns set foo 1
       $ ip netns
       foo (id: 1)
       init_net

  This is causing neutron to test if "qrouter-f00783d3-0e99-4fd6-a5b4-e058f857d77d" exists
  which fails because the output of ip netns list is "qrouter-f00783d3-0e99-4fd6-a5b4-e058f857d77d (id: 1)"

  Then tries to create qrouter-f00783d3-0e99-4fd6-a5b4-e058f857d77d which fails becasue the namespace
  already exists.
