Doc Text:	This feature adds the capability to configure the Cinder Dell EMC StorageCenter driver to use a multipath for volume-to-image and image-to-volume transfers. The feature includes a new parameter `CinderDellScMultipathXfer` with a default value of `True`. Enabling multipath transfers can reduce the total time of data transfers between volumes and images.

Rajini, can you handle the upstream backports? They will be needed on stable/rocky and stable/queens.

--- Additional comment from Tzach Shefi on 2018-10-31 13:32:19 UTC ---

OtherQA, no access to Dell's SC storage to verify post deployment's basic operation.

--- Additional comment from Rajini Karthik on 2018-10-31 13:38:52 UTC ---

Sure. I will backport them toda
