Draft: Rework input metadata handling in CutFlowSvc
This one is a bit tricky and I would appreciate some input from experts. The issue is that CutFlowSvc needs some information before any client wants to setup a cut.
The main change is I now consistently defer initialisation of CutFlowSvc. But it still does not work well in all cases, especially in CA-based config with shared writer.
