Creates a new tubeline for servers.
When a JAX-WS server deploys a new endpoint, it internally uses this method to create a new tubeline as a part of the initialization.
Note that this method is called only once to set up a 'master tubeline', and it gets {@link Tube#copy(TubeCloner) copied}from it.
@param context Object that captures various contextual information that can be used to determine the tubeline to be assembled.
@return non-null freshly created tubeline.
@throws javax.xml.ws.WebServiceException if there's any configuration error that prevents the tubeline from being constructed. This exception will be propagated into the container, so it must have a descriptive error.
