Gustavo Herzmann 6435d6c357 Dynamically retrieve the region one name from configuration

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.

api

DC Manager API is Web Server Gateway Interface (WSGI) application to receive and process API calls, including keystonemiddleware to do the authentication, parameter check and validation, convert API calls to job rpc message, and then send the job to DC Manager Manager through the queue. If the job will be processed by DC Manager Manager in synchronous way, the DC Manager API will wait for the response from the DC Manager Manager. Otherwise, the DC Manager API will send response to the API caller first, and then send the job to DC Manager Manager in asynchronous way.

Multiple DC Manager API could run in parallel, and also can work in multi-worker mode.

Multiple DC Manager API will be designed and run in stateless mode, persistent data will be accessed (read and write) from the DC Manager Database through the DAL module.
