[vdsm] strange network test failure on FC23

[David Caro]

I see though that is leaving a bunch of test interfaces in the slave:


2753: vdsmtest-gNhf3: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc noqueue state UNKNOWN group default 
    link/ether 86:73:13:4c:e2:63 brd ff:ff:ff:ff:ff:ff
2767: vdsmtest-aX5So: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc noqueue state UNKNOWN group default 
    link/ether 9e:fa:75:3e:a3:e6 brd ff:ff:ff:ff:ff:ff
2768: vdsmtest-crso1: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc noqueue state UNKNOWN group default 
    link/ether 22:ce:cb:5c:42:3b brd ff:ff:ff:ff:ff:ff
2772: vdsmtest-JDc5P: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc noqueue state UNKNOWN group default 
    link/ether ae:79:dc:e9:22:9a brd ff:ff:ff:ff:ff:ff



Can we do a cleanup in the tests and remove those? That might collide with
other tests and create failures.
