Remarks
Dehydration and Hydration of a running workflow is required as it takes long time to process and usually it may involve different parties or actors to take action and process different part of the workflow.
In order to persist and reload the running workflow (process) into and from a durable storage this interface is used.
This behaviour allows the running workflow when reaches a ReceiverNode that is part of ListenerSplitNode be stored into a storage.
Also when a WorkflowEngine using a WorkflowEventsManager picks that stored process to be resumed, it loads the WorkflowExecutionContext and continues the execution from the last point it went to hydration.
