Take advantage of ganeti hotplug

No race condition. No need for ther NetworkInterface to have an
operstate. Hook runs during instance-modify and depicts the currently
existing nics. No reboot needed modification to take place.

Later in mutliple backend mac prefix handling should be done by synnefo....
