Enhancement Request: Add new filter KeepBySource #25

This filter is similar to the existing DropBySource. The fate of the record is decided by the condition.

The condition can be used to join two datasets and only keep the records that are matched on the name (s) of the field that are joined.

Very useful for large data warehouse operations.
