Need a way to promote deployment to deployment config and other way around

Upstream deployments are almost identical feature wise with our deployment configs (except hooks and custom strategy). Additionally upstream deployments does not run deployer job which makes them faster to rollout, but less feature rich (hooks).

It would be nice to have a command to convert a deployment config into deployment or promote a deployment to deployment config if users need more features (hooks/custom deployments).

This command should be able to run in batch (I want to convert all deployment configs without hooks to deployments including converting the ICT to annotation trigger and setting lookup policy for images?).
