> Add possibility to SparkOptions to turn off spark RDD caching. There are use cases when its faster to recompute whole RDD rather then serialize, store, deserialize, read from store.
> We probably don't want to have some list of `PCollections` which we don't want to cache, because that would be tailored to specific runner and would be against Beam's concepts. So I propose to turn off caching for the whole pipeline.
