Promoted builds plugin / jenkins not deleting artifacts

[kab...@thoughtworks.com]

Hi -

I created the following issue 

https://issues.jenkins-ci.org/browse/JENKINS-28959

For now I'm hoping there's a work-around - can anyone with good knowledge of Jenkins suggest a way to clear out old promoted build archives automatically? They are filling up our disk space and causing issues with our CI server.

We are rotating builds, so builds are cleared out, but even though only 10 "promotions" show in the UI, the old promotions remain on disk.

Any suggestions welcome...
