ION version in interoperability test should be upgraded
We are currently testing with ION 4.0.0. This should be updated to the newest version 4.1.x
There seems to be some incompatilbility with the currently-used ION initialization and dtn://
EIDs (bundles are not forwarded anymore?), so a simple update of the version number is not enough.
In the course of this we might want to switch to a pre-built Docker image to speed up the build.
