as a ovirt/rhev user, i would like to use the cloudinit integration described at http://www.ovirt.org/Features/Cloud-Init_Integration from foreman
that means applying a user_data template and have it applied when deploying a ovirt/rhev vm from template
changes need to be done at the following level
-rbovirt to pass a specific body when using vm_action with 'start' action

-fog to pass a user when using vm.start

-foreman to handle user_data and pass it to setComputePowerUp in app/models/concerns/orchestration/compute.rb

make those changes invisible to other compute ressources
have the two first changes ready , working on the last one
