cached side inputs between tasks.

> We did some profiling of a spark job and 90% of the application time was
> spent on side input deserialization.
> For spark, an easy fix is to cache materialized side inputs per bundle. This
> improved running time of the profiled job from 3 hours to 30 minutes.
