Add Yetus InterfaceAudience annotations to Parquet

Parquet should use [Yetus InterfaceAudience annotations](https://yetus.apache.org/documentation/in-progress/audience-annotations-apidocs/org/apache/yetus/audience/package-summary.html) to specify its API's intended [audience](https://yetus.apache.org/documentation/in-progress/audience-annotations-apidocs/org/apache/yetus/audience/InterfaceAudience.html) (public/private) and optionally [stability](https://yetus.apache.org/documentation/in-progress/audience-annotations-apidocs/org/apache/yetus/audience/InterfaceStability.html) (unstable/evolving/stable) in code annotations both for the benefit of its users and also for ensuring that no breaking changes happen in the public API.
