missing steps for deployment in a self-provisioned K8s cluster

Currently, the deployment steps documented work for local or managed-k8s on cloud.

What's missing is steps for chaincode deployment over self-provisioned K8s cluster with a custom private registry. For example, with AWS and ECR as a reference K8s architecture, we could demonstrate the same.

Start by reviewing the existing documentation for local and managed Kubernetes deployment, then identify where chaincode deployment steps belong. Add a self-provisioned Kubernetes path using a custom private registry, with AWS and ECR as the reference architecture. Done means a newcomer can follow the documented steps end to end.
