> As a first step towards to a ReplicationManager I propose to introduce the EventQueue to the StorageContainerManager and enable to send SCMCommands via EventQueue.
> With this separation the ReplicationManager could easily send the appropriate SCMCommand (eg. CopyContainer) to the EventQueue without hard dependency to the SCMNodeManager. (And later we can introduce the CommandWatchers without modifying the ReplicationManager part)
