    Stack updated error if creation fails

    template https://github.com/openstack/heat-templates/blob/
    67301b6ff45b9f1c220ee0a0ab3aecd3a415032b/cfn/F17/
    AutoScalingCeilometer.yaml
    can have update error when execute on some resources
    which did not even created due to creation failed.

    Add check logic in _needs_update to make sure even resource still
    stay in init complete state can proceed update process by
    raise resource.UpdateReplace.

    For nested stack, StackResource should have the same status check
    logic in _needs_update method to avoid this error occur(nested()
    is None due to resource in failed state after create failed).
