Allow Users to specify Guest shutdown behavior for Stop, Rescue, and Delete (partial?)
Currently in libvirt stop, rescue, and delete operations simply destroy the underlying VM. Some GuestOS's do not react well to this type of power failure, and so it would be better if these operations followed the same approach as soft_reboot and give the guest as chance to shutdown gracefully. Even where VM is being deleted, it may be booted from a volume which will be reused on another server.
This change exposed a clean / forced option to the users for those operations, mirroring soft and hard reboot
The BP will be implemented as a sequence of changes:
1) Make compute manager perform a controlled stop by default, including ability to provide per image timing configuration via image metadata and livirt implementation
2) Extend the "force shutdown" parameter back through the rpcapi
3) Extend the V2 API to expose force shutdown as a user option
4) Add force shutdown to the V3 API
Step 1 delivers value in its own right (it prevents a potential data corruption issue) and so can be reviewed and merged without waiting for the subsequent steps.
