Review comment:
I don't think that we should store `ObjectListener` and `ErrorFactory` in
the holder of the options.

> Key: DRILL-7572
> URL: https://issues.apache.org/jira/browse/DRILL-7572
> Project: Apache Drill
> Issue Type: Improvement
> Affects Versions: 1.18.0

> Priority: Major
> Fix For: 1.18.0

>
> DRILL-6953, PR #1913 provides an EVF-version of the JSON reader. The original
> plan was to commit a first draft, with the feature disabled, then evolve from
> there. Review comments suggested we ensure that the first PR pass all unit
> tests with the feature enabled. Another comment suggested the JSON parser
> portion be reusable for other format or storage plugins. All good ideas.
> The amount of change in the original PR was becoming too large. So, we'll go
> ahead and split the work into smaller portions.
> This ticket is for the "JSON structure parser." This parser accepts the token
> stream from the Jackson parser and provides a framework to create a tree
> structure that describes the data. To keep the code simple, to simplify
> tests, and to make review easier, the structure parser does not directly
> integrate with the rest of Drill. Instead, it provides a number of listener
> interfaces which the next level implements. (The next level will be in
> another PR.)
