Dcorch-engine stops auditing the subclouds after the upgrade.
This is because audit_status of subcloud_sync data was not
set during data migration.
This update sets audit_status to initial state of “none”.
Test: Upgrade controller-1, and then swact to controller-1.
Verify the dcorch-engine audits subclouds.
