Revert to EventLoopMgr instead of HLTControlFlowManager when using GaudiPython in PyConf
goes together with Moore!3511 (merged)
created on top of !4578 (merged)
HLTControlFlowManager is not efficient enough when looping over events from python and running them one at a time This translated to a limitation of ~10 evts/s compared to ~500 with HLTControlFlowManager
