SA360 SFTP multiple file upload #25
Description
Add ability to upload multiple files to SA360 SFTP server in one function call by passing in an iterable or map of local files/remote files
Similar functionality as our AWS S3 multiple upload/download handling.
I suspect we can turn the filename mapper into a utility function that can be used by any functions that want multiple upload/download functionality and refactor our S3 connectors to use that as well as this SFTP feature.
