[openstack-dev] [Solum/Heat] Is Solum really necessary?

I think Heat is an ingredient for Solum. When you build a PaaS, you
need to control the app at different levels:
#1 describing your app (basically your stack)
#2 Pushing your code
#3 Deploying it
#4 Controlling the runtime (restart, get logs, scale, changing
resources allocation, etc...)
I think Heat is a major component for step 3. But I think Heat's job
ends at the end of the deployment (the status of the stack is
"COMPLETED" in Heat after processing the template correctly). It's
nice though to rely on Heat's template generation for describing the
stack, it's one more thing to delegate to Heat.
In other words, I see Heat as an engine for deployment (at least in
the context of Solum) and have something on top to manage the other
