This has been requested for a long time, and there have been several previous discussions, which all ended up in debating the implementation, rather than focussing on the simplest possible way to meet the user requirement. I think this latest attempt provides a simple way to meet the requirement, improves out CFN compatibility, and is inspired by an interface which has been proven to work. So I'm +1 on going ahead with this - the implementation looks pretty simple :) We've debated Jinja and other solutions before and dismissed them as either unsafe to run inside the heat service, or potentially too complex - this proposed solution appears to resolve both those concerns.
