1. Fix regression with live migration on shared storage …

   The commit c1ccc1a introduced
   a regression when NUMA live migration was done on shared storage
   
   The live migration support for the power mgmt feature means we need to
   call driver.cleanup() for all NUMA instances to potentially offline
   pcpus that are not used any more after the instance is migrated away.
   However this change exposed an issue with the disk cleanup logic. Nova
   should never delete the instance directory if that directory is on
   shared storage (e.g. the nova instances path is backed by NFS).
   
   This patch will fix that behavior so live migration will function
   
   2023.x only: Conflict resolved in compute/manager.py due to
   bluperint libvirt-mdev-live-migrate is not in 2023.x and the related
   unit test is removed.
