PARQUET-807: Allow user to retain ownership of parquet::FileMetaData. Also implements PARQUET-808: opening file with existing metadata object. This allows a user to create a reader only for the purposes of obtaining the metadata. Do you all think it's worth having a convenience method for reading the metadata out of a file?
