Code Issues Proposed changes

Add cinder backend driver for Huawei FusionStorage 

It will support the minimum set of features required in Cinder:
  - Volume Create/Delete
  - Volume Attach/Detach
  - Snapshot Create/Delete
  - Create Volume from Snapshot
  - Get Volume Stats
  - Copy Image to Volume
  - Copy Volume to Image
  - Clone Volume
  - Extend Volume
