> Currently service upgrade involves 2 steps
>  * initiate upgrade by providing new spec
>  * trigger upgrade of each instance/component
>  
> We need to add the ability to upgrade the service in one shot:
>  # Aborting the upgrade will not be supported
>  # Upgrade finalization will be done automatically.
