  Creates Cinder volumes.
  Cinder volume is a storage in the form of block devices. 
  It can be used, for example, for providing storage to instance. 
  Volume supports creation from snapshot, backup or image. 
  Also volume can be created only by size.
  The template creates volumes for vSON DC leaders
  (Virtual Function Component DCL).
