If a primary role container is unhealthy, we might take a while to timeout the health check poller. In the meantime if we have started the other roles, they'll be running tow containers. This could be a problem, especially if they read run jobs as that doubles the worker capacity which could cause exessive load. We'll wait for the first primary role container to boot successfully before starting the other containers from other roles.
