I was disappointed (not that I'm picking on them) to learn Hashicorp's terraform didn't do exactly the sort of abstraction you're talking about. You can cobble together layers of automation, but I share your disappointment that there's not a single solution. Although I will say rackn's digital rebar gets a lot of the way there. You can deploy workloads in a pretty technology-agnostic fashion for the things it does support, and it can be integrated/extended with ansible, terraform and other scripting tools (including plain old bash) or other languages as needed.
