flowdetails meta is not visible publicly from the engine

[Greg Hill]

We have need to get at the flowdetails 'meta' field from objects that only have access to engine.storage. We *can* do engine.storage._flowdetail.meta to get it, but relying on a private attribute seems problematic. I propose that the Storage object should expose the underlying flowdetail object as a public attribute.

@property
def flowdetail(self):
    return self._flowdetail

Is there something I'm not considering here? The use-case we have is to get some flow metadata from a Listener object that will get the flow_factory information from flowdetail.meta['factory']
