    Auto-confirming resizes would bail on exceptions

    Fixes bug 971939

    Fixes a few things. If instance went to error, we should set the
    migration to error so we don't retry. Also, if we get any other
    exceptions when trying to confirm resizes, we should not bail out of the
    loop. Also: be nice to other greenthreads and yield on each iteration.

    Includes complete unit test for xenapi poll_unconfirmed_resizes which
    didn't exist prior to this patch.
