setup-data-libraries cannot update a data library without --legacy

[hexylena]

setup-data-libraries -i data-library.yaml

and

setup-data-libraries -i data-library.yaml --legacy

behave quite differently.

I want to use the new batch upload API. It's way faster and the result is much more human friendly. But we are stuck using the --legacy API, because if you run without the --legacy flag, then it creates a duplicate data library.

Having a period of time with a duplicate (or with no) data library is not ideal.

1. Could the batch upload API update a data library rather than producing a new data lib?
2. Otherwise, could we get the nicer short names in the --legacy api?

@mvdbeek it's this one :)

that's a limitation of the fetch data API, transferring to galaxy
