This commit removes the hardcoded "RegionOne" region name and instead
retrieves the region name dynamically from the service configuration.
This change prepares for a future update where DC services will be
deployed on a standalone system that uses a UUID as the default region
name.
Test Plan:
01. PASS - Add a subcloud.
02. PASS - Manage and unmanage a subcloud.
03. PASS - List and show subcloud details using subcloud list and
subcloud show --detail.
04. PASS - Delete a subcloud.
05. PASS - Run 'dcmanager strategy-config update' using different
region names: "RegionOne", "SystemController", and without
specifying a region name. Verify that the default options are
modified accordingly.
06. PASS - Run the previous test but using 'dcmanager strategy-config
show' instead.
07. PASS - Upload a patch using the dcorch proxy (--os-region-name
SystemController).
08. PASS - Run prestage orchestration.
09. PASS - Apply a patch to the system controller and then to the
subclouds
10. PASS - Review all dcmanager and dcorch logs to ensure no
exceptions are raised.
