> Introduce config: task.elasticity.factor which defaults to 1. If elasticity factor = 1 then each task consumes the whole input SSP. If elasticity factor = X, then each task is split into X elastic tasks and each elastic task consumes 1/X th of the input SSP. Each of the 1/X th of the input SSP is referred to as the sub-SSP.
> Additionally, introduce sub-SSP concept as SystemStreamParitionKeyHash where each SSP has X KeyHashes.
