Review comment:
All PCollections in the pipeline that is being executed will be marked as
computed once a job (main job or background caching job) completes.
So it looks like this:
pcoll_a, pcoll_b belongs to pipeline
pipeline runs into job, returns a pipeline result (main job) or a
BackgroundCachingJob (backgroun caching job).
Say pcoll_a and pcoll_b are not depending on each other, and the user
invokes `show(pcoll_a)`.
A pipeline fragment that only contributes to pcoll_a will be executed.
Once pipeline result is in a successful state or
BackgroundCachingJob.is_done(), pcoll_a is marked as computed.
