Enhance Deployment Pipeline for Approval Process

[Rolika4]

In order to improve the deployment process, we need to implement a feature that allows for the visualization of deployment differences before proceeding. The key requirements are:

1. Integrate a mechanism within the deployment pipeline that presents the differences in the deployment to the user.
2. Provide an option for the user to approve or decline the proposed deployment.
3. If the user approves, proceed with the deployment.
4. If the user declines, the system should automatically revert the application set to its previous state.

This enhancement aims to increase the transparency and control of the deployment process, ensuring that changes can be reviewed and approved before being made live.

Acceptance Criteria:

1. The deployment pipeline must be able to display the differences in the deployment clearly to the user.
2. The user should have the option to either approve or decline the deployment.
3. On approval, the deployment should proceed as planned.
4. On decline, the system must automatically revert the application set to its previous state without any manual intervention.
5. Documentation should be updated to reflect the new deployment process.
