This script creates the necessary files under /var/run/heat-config so that the
next time configure.d/55-heat-config is executed via os-refresh-config, no
deployments that were already known are rerun.
This is a workaround for https://bugs.launchpad.net/heat-templates/+bug/1513220
in scenarios where /var/run/heat-config has already been lost due to a scenario
such as a system reboot.
This script is a manual workaround, and should only be executed on instances
where it's known that the deployments do not need to be reapplied.
