Shorten parallel builder thread name to artifactId, conditionally with groupId

Following up on MNG-6471, the thread name that is now generated can easily exceed 60 chars or more, e.g.:

[mvn-builder-de.somecorp.foo.barbazx:register-server:jar:2.0.0.local-dev3] ...

This devaluates -Dorg.slf4j.simpleLogger.showThreadName=true as the only easily availble option to differentiate where a logline comes from.

As discussed here (and in the following comments), one idea is to make the pattern configurable (or simpler, have a toggle to include the entire module id or only its artifactId).
A slightly different approach could try to detect whether there are "duplicate" artifactIds in the reactor and only append the groupId for those.
In any way, type, classfier and version don't seem to add anything valuable.
