Which use case/requirement will be addressed by the proposed feature?

Right now, the column.exclude filter mode is set to CATALOG. In DBZ-6775 we stored the shard in the catalog name. This means that the column exclude list needs to use the shard or wildcard. eg -80.table.column. We should switch to SCHEMA filter so we can do keyspace.table.column style filter expressions. Shard doesn't matter and wouldn't make sense to exclude based on that. 

Implementation ideas (optional)
