Title:
  _resize files are not cleaned when we destroy instances after failed
  resize because of disk space

Status in OpenStack Compute (Nova):
  Invalid

Bug description:
  I configured my setup to work with preallocation. 
  I resized instances and they fail to resize on disk space. 
  when you destroy the instances the _resize file is not removed from the /var/lib/nova/instances dir:

  [root@orange-vdsf instances(keystone_admin)]# ls -l /var/lib/nova/instances/

  running qemu-img info I can see that the disk is not deleted as well:

  [root@orange-vdsf instances(keystone_admin)]# qemu-img info /var/lib/nova/instances/1a98eefe-ba41-49b7-931a-ebe54796e343_resize/disk
  image: /var/lib/nova/instances/1a98eefe-ba41-49b7-931a-ebe54796e343_resize/disk
  file format: raw
  virtual size: 1.0G (1073741824 bytes)
  disk size: 1.0G
  [root@orange-vdsf instances(keystone_admin)]# 

  (the instances were launched with tiny flavour which is 1GB).
