Description
We need to override the deployment stages to allow centurion to enable controlled container shutdown during a deploy.
For example, we have a service container that is running a set of background tasks. On a deploy, we need centurion to notify the service that a shutdown is requested. Then, centurion should monitor a status endpoint until the service indicates that all background processes have terminated. At that time, centurion will be clear to bring down the container and deploy the new image.
