    hyperv: Cleans up live migration Planned VM
    
    If an instance having iSCSI volumes attached is being
    live-migrated, a Planned VM is created at the destination.
    If the live-migration fails, the Planned VM is not cleaned
    up at the destination.

Title:
  Hyper-V: planned vms are not cleaned up

Status in compute-hyperv:
  Fix Released
Status in OpenStack Compute (nova):
  In Progress
Status in os-win:
  New

Bug description:
  We create a planned vm during live migration when having passthrough
  disks attached in order to properly configure the resources of the
  'new' instance.

  The issue is that if the migration fails, this planned vm is not
  cleaned up.

  Although planned vms are destroyed at a second attempt to migrate the
  instance, this issue had an impact on the Hyper-V CI as planned vms
  persisted among CI runs and vms having the same name failed to spawn,
  as there were file handles kept open by the VMMS service, preventing
  the instance path from being cleaned up.
