   This PR touches a lot of places (i.e. each query engine integration) since it relies on the mechanism to propagate table props to the Parquet reader builder. We have something similar for our write options.
   
   We have to be careful with serialization since table properties can be Guava `ImmutableList` that will cause troubles for custom serialization mechanisms that query engines may use (e.g. Kryo). If I remember correctly, Spark still uses Java serialization for its tasks but I am not sure about other query engines. That being said, we already propagate write properties so the issue (if any) is already there.
