Blue/Green Deployment

Users can perform blue/green deployments using Ingress or Service.

Adding a blue/green deployment means creating a new K8S Ingress or K8S Service that can replace two Helm releases with each other.

Only two Helm releases with the same Project, Cluster, Namespace, Release Type, Chart Name, Chart Version, and Development Classification can be linked.
