Issue

Servers in nova list get renamed on a minor upgrade of Red Hat OpenStack Platform 8 and OpenStack Director does not seem to respect the custom names from HostnameMap any longer.

From scheduler_hints.yaml:

HostnameMap:
   overcloud-controller-0: custom-controllername-01
   overcloud-controller-1: custom-controllername-02
   overcloud-controller-2: custom-controllername-03
   overcloud-novacompute-0: custom-computename-001
   overcloud-novacompute-1: custom-computename-002
   overcloud-novacompute-2: custom-computename-003

Before the minor upgrade:

| b45330a7-6020-4f24-8178-1419aee9df1b | custom-computename-001  | ACTIVE | -          | Running     | ctlplane=192.0.2.158 |

After the minor upgrade:
