[MNG-1977] Global dependency exclusions

**[Kees de Kooter](https://issues.apache.org/jira/secure/ViewProfile.jspa?name=kdekooter)** opened **[MNG-1977](https://issues.apache.org/jira/browse/MNG-1977?redirect=false)** and commented

I depend on some libraries, which in turn depend on something
(which in turn depend on something) that I don't want, because I declare
some other artifact in my pom.xml.

A concrete example: I don't want that the artifact "xerces" is imported in
my project because I declare to depend on "xercesImpl" which ships newer
libraries but with the same namespaces.

I guess I would need an "exclude transitive dependency at all", either
globally or from this and that artifact. I saw the \ tag, but it
forces me to be very verbose and have exact control on what is required by a
dependency.
