RFC - Lifecycles

Lifecycles in Octopus are a new feature designed to streamline the deployment process by introducing structured phases for automated and manual promotions between environments. Each lifecycle is composed of phases that define specific triggers and rules, such as automatically promoting from development to test environments or requiring manual deployment to production. The feature enables complex deployment scenarios, such as preventing production deployments until successful staging is confirmed or flagging problematic deployments to halt progression. Lifecycles also allow for automatic release creation from NuGet packages, thereby enhancing automation without external integration. Additionally, project groups will now focus solely on organizing projects, as lifecycles will manage environment deployment permissions and retention policies. The introduction of lifecycles is expected to simplify and enhance deployment workflows by providing a more controlled and flexible framework.
