Zhang Rong(Jon) e422731760 Fix unable to determine the SPG sync state if one site is down 
If Site1 (the local site) is down while setting up the protection
group, the subcloud peer group sync state is unable to determine.
This commit will automatically create the non-primary association on
Site2 (the peer site) when creating a primary association, and
update the sync state to the non-primary association. Then the
operator can check the sync state on Site2 if Site1 is down.

Test Plan:
- PASS: Create a primary association and check the non-primary
        association on peer site. It was created, and sync_status
        will follow the primary association's sync_status.
- PASS: Delete the primary association and check the non-primary
        association on peer site. It was deleted.
- PASS: If you restart the "dcmanager-manager service" in the local
        site while the association sync_status is in "syncing", the
        sync_status will transition to "failed".
- PASS: Create a primary association and wait for the sync_status
        change to "in-sync". Delete the subcloud peer group on peer
        site, the deletion will fail because it is associating to
        the non-primary association.

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.
