Switch to fixed tags of Detector compact geometry in production
Currently, when running the dd4hep builds, we are using the trunk version of the compact geometry from the Detector project. Whilst not exactly equivalent this is akin to using the master branch of DDDB in the old DetDesc builds. Once we start using the dd4hep builds in production, either at the pit or on the grid offline, we need to switch to fixed ‘tags’ of the geometry.
