@fhueske , i"m favor of showing the whole plan. First, `Table` API converts
`DataSet` to a `Table` and provides several operations on the `DataSource`.
It's a data-processing level and part of the DataSet. Showing the whole plan
will help user know better with the DataSet program completely. Second,
`getExecutionPlan` returns the plan from initial DataSource to final
`DataSink`. According to my limited comprehension, it's not easy to figure the
query operations out only.
> Add explain support to print ast and sql physical execution plan.
