> *Problem*:
> As part of rebalance, we always expire the current work assignment and
> proceed to signal consensus and start the container with new work assignment.
> It is inefficient for the processors to do the above when there is no changes
> in the work assignment between the active job model & the proposed job model.
> *Changes*:
> Processors perform onJobModelExpired and onNewJobModel only if there are
> changes to their work assignment across the active and proposed job model.
