Comment 3 for bug 1715379

The bug arises from this https://github.com/Juniper/contrail-server-manager/wiki/Provision-Contrail-4.0.1-(Ocata-Openstack-Containers)-on-a-single-node-all-in-one-cluster-using-Server-Manager#target-node-requirements-for-ocata-containers

Right now after re-imaging with SM we have to take manual steps to ensure that sources.list on the target nodes are fine and need to run apt-get update on each node before issuing provisioning

So this step needs to be automated.

Above commit should fix the issue.
