> With just the standalone pipeline, a new pipeline was created for each and 
> every container.
> This code can be optimized so that pipelines are craeted less frequently. 
> Caching using pipeline names will help with Ratis clients as well.
> a) Remove Container name from Pipeline object.
> b) XceiverClientManager should cache objects based on pipeline name
> c) XceiverClient and XceiverServer should be renamed to 
> XceiverClientStandAlone & XceiverServerRatis
> d) StandAlone pipeline should have notion of re-using pipeline objects.
