AWS Transfer Family

2022/02/23 - AWS Transfer Family - 2 updated api methods

Changes  The file input selection feature provides the ability to use either the originally uploaded file or the output file from the previous workflow step, enabling customers to make multiple copies of the original file while keeping the source file intact for file archival.
