Duplicate commons-io and org.apache.commons.io

[nedtwigg]

The Eclipse 4.26 repositories require commons-io:commons-io:2.11.0 (from mavenCentral) and Eclipse CDT requires org.apache.commons.io:2.8.0 from its own p2 repository.

Part of the problem is around the symbolic name Apache commons-io on mavenCentral has bundle symbolic name

• org.apache.commons.commons-io <- on maven central
• org.apache.commons.io <- in Eclipse CDT

This is easy to resolve by putting a filter on the CDT repository, but perhaps our p2 resolution ought to be able to handle this on its own, perhaps by special-casing this common artifact.
