Describe the problem/challenge you have

• Currently the charts live on develop.
• We don’t have chart to use unless we bump helm chart version. This make it difficult for testing.
• We don’t have a reliable way of testing the helm charts.
• We don’t have develop equivalent chart for the engines. Which is needed for testing.

We have broken this down in several use cases. These would be worked upon use-case wise.

• [x] - When a PR is raised with base branch as develop -> #557
• [x] - When a PR is raised with base branch as release/x.y -> #557
• [x] - When a release/x.y branch is created
• [x] - When a PR is merged to develop branch
• [x] - When a PR is merged to release/x.y branch
• [x] - When a release tag is created from release/x.y branch
