Move instance delete to new-world BDM objects

Move all the code paths related to instance deletion to new-world
objects. This includes soft- and hard- deletes, instance init on compute
startup, as well as the reclaim_queued_deletes and
_cleanup_running_deleted_instances  periodic tasks.

It introduces an additional database call in the _shutdown_instance
method as there are still paths that call this method but will not pass
it BDM objects. This will be removed as soon as _reschedule_on_error
(basically meaning instance spawn) code paths are moved to BDM objects.
