This commit enhanced dcorch find_missing algorithm so that the first
audit after subcloud becomes managed won't try to create resources that
have matches in the subcloud (otherwise the creation will fail for DB
duplication error). This is neccessary for resources that are created
at deployment time and existing resources not yet tracked by dcorch.
