Change config property/setting for add_record_metadata

[freimer]

Problem

Fixes issue #34 . wrong config property/setting was used to add metadata. It is add_record_metadata, not add_metadata_columns. Tested on my own data pipelines and it works with this simple change.

Proposed changes

Change config property/setting from add_metadata_columns to add_record_metadata
