> The {{JobMaster}} should be able to rescale a job or a subset of its 
> operators. In order to do that we have to expose RPC calls to trigger this 
> action.
> The rescaling works by first taking a savepoint, then suspending the old job, 
> rescale it and then restart it from the taken savepoint.
