Bug 7843 - Missing buckets in ELAN BC group installation during OVS restart

L2 pipeline can contain malformed flows/groups if OVS restart occurs in parallel
due to oper DS temp delete during restart
Possible solution would be to check for config DS inventory node instead of oper DS
so flows would be restored with correct content after the OVS is up again
