  [Hyper-V] Netmask value is not parsed by hv_set_ifconfig - IP

Bug description:
  This bug is a continuation to bug ID 1506521 - the refreshed
  hv_set_ifconfig script in Python3.

  On a Wily system with the new script, doing an IP injection does change the IP on the VM, however the netmask value is not parsed and gets ignored.
  It gets set to a default of 255.0.0.0.

  Kernel: 4.2.0-23-generic

  Attaching generated ifcfg-eth0 file that is used by this script.

  syslog doesn't record any related events to the netmask, and also
  manually executing hv_set_ifconfig against the generated ifcfg works
  with no errors.

  The interfaces files gets modified to this:
  iface eth0 inet static
          address 10.123.120.199
          gateway 10.123.119.1
          dns-nameservers anything_changed

  #End of hv_set_ifconfig stanzas
