Some deployments of the undercloud would like to use
net-config-noop (to disable all network configuration).
This patch changes this noop software deployment to use
'apply-config' instead of 'os-apply-config' which allows it
to work with the undercloud installer which only supports the
newer (apply-config) style due to heat signalling requirements.
