> Currently Function and ContextManager init is called per instance of the StreamOperatorTask. 
> When using an StreamApplication with the LocalApplicationRunner + ZkJobCoordinator, SamzaContainers are recycled when the JobModel is updated. 
> This will lead to init and close being called for Functions and ContextManager multiple times during the ApplicationRunner and StreamApplication lifecycle. This needs to be fixed.
