rhel-osp-director: After upgrading overcloud 7.3->8.0 the nova-compute has state "down" in the output from 'nova service-list'.


Environment:
openstack-tripleo-heat-templates-kilo-0.8.14-1.el7ost.noarch
openstack-nova-scheduler-12.0.2-4.el7ost.noarch
openstack-nova-conductor-12.0.2-4.el7ost.noarch
openstack-nova-compute-12.0.2-4.el7ost.noarch
openstack-tripleo-heat-templates-0.8.14-1.el7ost.noarch
python-novaclient-3.1.0-2.el7ost.noarch
openstack-nova-common-12.0.2-4.el7ost.noarch
openstack-nova-novncproxy-12.0.2-4.el7ost.noarch
python-nova-12.0.2-4.el7ost.noarch
openstack-nova-cert-12.0.2-4.el7ost.noarch
openstack-nova-console-12.0.2-4.el7ost.noarch
instack-undercloud-2.2.7-1.el7ost.noarch
openstack-nova-api-12.0.2-4.el7ost.noarch


Steps to reproduce:
1. Deploy 7.3 overcloud.
2. Upgrade it to 8.0
3. Run nova service-list.

Result:
[stack@instack ~]$ nova service-list
