Enable environment promotion for application code
Problem to solve
In response to HashiCorp's introduction of waypoint we need to improve the fit and finish of Vault and GitLab CICD. This is specifically around App Promotion
Proposal
Waypoint: We plan on building on this feature to enable workspaces that may target different infrastructures (such as a dev vs. production cluster) and we want to build features so applications can be easily "promoted" from one stage to another.
