[Rdo-list] Overcloud nodes host-name persistence

It seem that If you restart bare metal servers! there will be a problem after boot that the node will be register it self with a different name rather than the one used on deployment! as the attachment shown the failed compute node is registered with new name: => overcloud-novacompute-2.localdomain as it was => overcloud-novacompute-2 during deployment! I check: ``` [heat-admin@overcloud-novacompute-2 ~]$ sudo hostnamectl set-hostname --transient overcloud-novacompute-2 [heat-admin@overcloud-novacompute-2 ~]$ sudo hostnamectl set-hostname overcloud-novacompute-2 ```` but after reboot the server again append localdomain to iit's hostname Sincerely, Ali R.
