Can be moved to AbstractRowIndex class to return 0 by default. Override by
derived class like HyperRowIndex to have different implementation.

> Project: Apache Drill
> Issue Type: Sub-task
> Components: Tools, Build & Test
> Affects Versions: 1.11.0
> Reporter: Paul Rogers
> Assignee: Paul Rogers
> Fix For: 1.11.0
>
>
> Operators work with individual row sets. A row set is a collection of records
> stored as column vectors. (Drill uses various terms for this concept. A
> record batch is a row set with an operator implementation wrapped around it.
> A vector container is a row set, but with much functionality left as an
> exercise for the developer. And so on.)
> To simplify tests, we need a {{TestRowSet}} concept that wraps a
> {{VectorContainer}} and provides easy ways to:
> * Define a schema for the row set.
> * Create a set of vectors that implement the schema.
> * Populate the row set with test data via code.
> * Add an SV2 to the row set.
> * Pass the row set to operator components (such as generated code blocks.)
> * Compare the results of the operation with an expected result set.
> * Dispose of the underling direct memory when work is done.
