I wonder about the value. Isn't this problem space handled nicely by cfengine, chef, puppet, docker, vagrant and others? Rather than starting from scratch could you improve those existing systems? If however you some benefit that does not exist in those tools or, cannot be added to said tools I would look at it. My current host/node config solution is custom built around bash, curl and git with a trivial web-front in PHP.
