Refactor deploy

• adds inputs to enable the extension of other jobs; based on the idea that in most cases, deploy should be a wrapper of another component, usually iac/apply or container/release. A (no longer working) example can be found in archive/oiss-deployment.
• adds inputs to configure optional jobs for environment:action: <prepare | stop>
• removes script input to allow usage with trigger or run
• adds hidden command array to validate prod deployments (from @elio.romero)
