Subject: [PATCH] Add description when rename LUN in Huawei driver

Sometimes when we rename a LUN on the array, we should
add some description to record some information like
volume id on cinder side. This patch will enable this.

Closes-Bug: #1537304
Change-Id: Ib156e61b5b1e305c41426cf5c6001dd44770140c
