Bug description:
Hello!
I've encountered the bug when configuring nova-compute service on new node:

Steps to reproduce
------------------
1. Install and configure nova on controller node, make sure that all nova
services are running correctly
2. Configure nova on compute node:
follow Queens Series Release Notes
(https://docs.openstack.org/releasenotes/nova/queens.html), in [placement]
comment out deprecated 'os_region_name' and configure 'region_name'
3. Restart nova-compute service
Expected result
------------------
Nova-compute service started and running without errors
Actual result
------------------
Nova-compute service failed with PlacementNotConfigured error
Workaround
------------------
1. Comment out 'region_name' in [placement] and configure deprecated
'os_region_name':
[placement]
os_region_name = RegionOne
auth_type = password
auth_url =
project_name = service
project_domain_name = default
username = placement
user_domain_name = default
password =
#region_name = RegionOne
2. Restart nova-compute service, сheck your log
