Can you please add an example of the new Polling use in the class javadoc.
Thanks.

> # Current version of HcatalogIO is a bounded source.
> # While migrating our jobs to aws, we realized that it would be helpful to
> have an unbounded hcat reader that can behave as an unbounded source and
> polls for new partitions as and when they become available.
> # I have used splittable pardo(s) to do this. There is a flag that can be
> set to treat this as a bounded source which will terminate if that flag is
> set.
