Synchronizer failures on cord-2.0 branch

Building CiaB using the `cord-2.0` branch (following these directions) results in failures in a number of synchronizers: openstack, vtr, and vsg. These synchronizers exit immediately with a configuration issue:

AttributeError: ConfigParser instance has no attribute 'db_name'

It seems they are trying to read a non-existent config file. E.g., the openstack synchronizer is being invoked with this command:

command: bash -c "sleep 120; cd /opt/xos/synchronizers/openstack; python ./xos-synchronizer.py -C /root/setup/files/openstack_synchronizer_config"

But the referenced config file does not exist in the container.
