Title:
  Remove unnecessary steps for cold snapshots

Status in OpenStack Compute (Nova):
  Fix Released
Status in OpenStack Compute (nova) havana series:
  Fix Released

Bug description:
  When creating cold snapshots we first stop the instance, create a snapshot of that instance, extract the snapshot to a file, delete the snapshot and bring the instance back up.
  If the instance is stopped, then there's no need to create a snapshot because there's no concurrent writer, so the snapshot can be extracted directly and save us from the two unnecessary steps (creation and deletion of a snapshot).
