HadoopInputFile to pass down FileStatus when opening file

[steveloughran]

Rationale for this change

• Saves overhead of HTTP head request when opening a file
• tells the hadoop FS client that the file being opened is parquet, and should use the first recognized policy of "parquet, columnar, vector, random". These can disable prefetch and limit ranges requested to those optimal for columns.
