Continuously Observe Physical Resources

Registered by Clint Byrum

Convergence brings the ability to update the template at any time, and de-couples observing of physical resources (a.k.a. "reality") from taking action on those physical resources. However, once stacks are created or updated and reach a steady state, the physical resources may continue to change. Rather than wait for a user to issue an update to deal with those, the observer engine can subscribe to notifications and poll backends, and issue convergence actions when physical resources change state.
