While trying to upload a target folder which contains a link to a directory, cloudexec launch will fail during the upload step with the error:

2023/05/17 10:43:18 error uploading files: unable to read file target/link-to-directory: read target/link-to-directory: is a directory

Ideally, if the link is valid then cloudexec would follow the link and upload the files it contains.
If the link is invalid, we could log a warning and ignore it.
