Title:
  Support static network configuration even on already configured
  devices

Status in Ubuntu:
  Confirmed
Status in linux-gcp package in Ubuntu:
  Confirmed

Bug description:
  Some datasources (e.g. OpenNebula) support full static network
  configuration. It's done in local execution phase by pushing new
  interfaces configuration to *distro.apply_network*. This new
  configuration is written on disk and activated by calling ifup on
  particular devices. Unfortunatelly  it can't be guaranteed that full
  local phase is executed before any network configuration is done by
  system. Mentioned steps are OK only for devices not present in former
  network configuration or not configurated to start on boot (e.g. eth0
  configured on boot to take address from DHCP, the new static
  configuration is not applied on this device, it's already up and ifup
  just passes).

  It would be good to first put interfaces down before writing new
  configuration.
