Need to remove "set -e" https://github.com/Juniper/contrail-container-builder/blob/master/containers/openstack/heat-init/entrypoint.sh#L3

since `read` calls in /common.sh returns exitcode 1 even on a successful read since it had hit the EOF

FYI, from read manual
` The return code is zero, unless end-of-file is encountered `
