Use virtio driver for fuel-master NIC

Using e1000 driver on fuel master may lead to temporarily loss of
communication [1]. We can use two approaches here:

  * use virtio driver
  * install e1000-kmod package

virtio driver should be sufficient for our purposes, we don't use
bonding on fuel master.

e1000-kmod package is available on fuel master and provide e1000 kernel
module which does not introduce additional problems. This package is not
installed by default but for this purpose MASTER_NODE_EXTRA_PACKAGES
cmdline option can be set during fuel master installation.
