[BUILD] Prevent the core from exporting commons-io

and instead let every project get it by itself, since it is not part
of the cores public api and it further reduces the coupling between
the core and these projects.

We decided that this should be a separate commit from the previous
ones (that also change the build-system) since it changes different
files and could not be integrated coherently.
