DRILL-6114: Metadata revisions
This PR is part of the "[batch handling
updates\https://github.com/paul-rogers/drill/wiki/Batch-Handling-Upgrades]";
project. It completes the new internal metadata system by including support for
the remaining vector types: unions, lists and repeated lists.
The metadata code was refactored. Previously, it was small enough to fit
into a single file (with nested classes). With the added complexity, the
metadata classes were split out into separate classes, grouped into its own
Java package.
A few fixes were made here and there to ensure the unit tests pass.
@ppadma or @bitblender, can one of you run the pre-commit tests and send me
the details of any failures?
