Review comment:
What do you think about my previous comment? If you agree, you should say at
the deprecations to use the `Types` factory instead of directly creating
`PrimitiveType` objects.

> a new representation for logical types. As of now this is not yet supported
> in parquet-mr, thus there's no way to use parametrized UTC normalized
> timestamp data types. When reading and writing Parquet files, besides
> 'converted_type' parquet-mr should use the new 'logicalType' field in
> SchemaElement to tell the current logical type annotation. To maintain
> backward compatibility, the semantic of converted_type shouldn't change.
