Review Comment:
   We don't have old schema in code now. 
   So, creating a parquet file as per old schema, adding rows etc will be a big 
chunk of code. 
   
   I observed that we do maintain puffin files, delete files and metadata files 
in resource folder
   
https://github.com/apache/iceberg/tree/main/core/src/test/resources/org/apache/iceberg
   
   Hence, I kept it to avoid PR code size.
