Changeset 5593 for branches/HeuristicLab.Hive-3.4/sources/HeuristicLab.Services.Hive/3.4/LifecycleManager.cs

#1233

• changed the way lifecycle methods are called. The new service method TriggerLifecycle checks when the latest cleanup was made and performs one (if necessary). This can also be called by an external program (like a windows task)
• robustified logging
