move cloud-run-user-script.conf to cloud-final, use cloud-cfg for invoking

This moves what was done as cloud-run-user-script.conf to 'cloud-final'
and makes that re-use the cloud-init-cfg code, but simply with a different
set of default configs.

Also, adds keys_to_console and final_message cloud-config modules
