Title:
  Evacuated instance disk not deleted for non shared storage

Status in OpenStack Compute (Nova):
  Fix Released

Bug description:
  After instance evacuated from failed host and cleaned up during host boot in nova.compute/manager._destroy_evacuated_instances, the instance is removed but it's disk files are always kept in the filesystem.
  In case of shared storage it is correct behavior, but in case of non shared storage the disks should be removed.
  They not just consuming storage but also prevent from instance to be migrated back to the host in case of need.
