virtual_fuel: add XML tree as attribute of VirtualFuel
With this patch, the VM XML definition tree is an attribute of the object, this way it can be used by all methods without having to re-read the file. Methods added: update_vm_template_file: Flushes the contents of the in-memory XML representation of the VM to the backing file.
