PipelineRequest
Represents an HTTP request to be sent to a cloud service.
            The type of a  PipelineRequest is specific to the type of the
             PipelineTransport used by the  ClientPipeline
            that sends the request.  Because of this,
             CreateMessage is used to create an instance of
             PipelineRequest for a given pipeline.
