User Request: Fine grain control of uploading/downloading

[johnbradley]

... It would be nice, for example to have finer control over where a file should be placed when either uploading to or downloading from dds.

The upload and download commands work from the standpoint of uploading or downloading an entire project. For download there are include and exclude parameters for filtering what is downloaded but it still works for the entire project.

One option would be to introduce a copy command similar to the aws s3 cli:

aws s3 cp test.txt s3://mybucket/test2.txt

This functions as both upload and download.

https://docs.aws.amazon.com/cli/latest/reference/s3/cp.html#examples.

Instead of s3 we would need a dds prefix. So something like this:

ddsclient copy test.txt dds://myproject/test2.txt

We currently use this dds prefix to reference files in bespin-cli: https://github.com/Duke-GCB/bespin-cli#user-edits-job-template-file
