Scenario Bundles: It should be possible to add IRIs that link to external datasets

[han-f]

Description of the issue

We recall that we discussed at some point that it makes sense to be able to also link to external datasets in some cases. This may make sense when people publish data elsewhere but provide scenario bundle information on the OEP as required in the 8th EFP.

Ideas of solution

Allow for external IRI and external dataset name for input and output data under "scenario".
