[Sheepdog] [PATCH 0/3] fix vdi deletion bugs

[MORITA Kazutaka]

This patchset fixes vdi deletion bugs which happens when
 - the number of nodes is larger than the number of object copies
 - we pass a non-numeric value as a snapshot id to 'collie vdi delete'


MORITA Kazutaka (3):
  sheep: pass a correct parameter to read_object()
  sheep: return the error reason in start_deletion()
  support deleting a snapshot vdi with a tag name
