    Fix automatic confirmation of resizes for no-db-compute
    
    compute/api.py:confirm_resize() was still making a bunch of calls
    against the database that were tripping over the no-db-compute
    enforcement checks. Instead of trying to unwind all of the instance
    action, quota, etc code and divert to conductor, just farm out the
    entire confirm_resize() call to conductor.
    
    Fixes bug 1161402
