Comment 11 for bug 1585275

Looks like we are hitting this in stable/newton:
https://build.opnfv.org/ci/job/apex-deploy-virtual-os-odl_l2-nofeature-ha-master/749/console

DB sync errors there. Need to do more testing to confirm. If this is still a problem, we will figure out a way to order DB syncs after galera cluster check with the composable model.
