    buildmaster: replace horizons with JanitorConfigurator
    
    The old c['logHorizon'] way of configuring is not supported anymore, we
    should use JanitorConfigurator. A new __Janitor builder will be created
    to help keep an eye on the cleanup activities and for that we need
    buildbot-worker package as well.
