Create deployment files to deploy the prod version of wishlist

[rsaim]

As a Developer I need deployment files to deploy the prod version of wishlist and postgres service to nyu-cluster on IBM Cloud So that we can deploy the prod version of wishlist to prod Kubernetes namespace

Details and Assumptions

• nyu-cluster Kubernetes cluster is already created on IBM Cloud
• prod Kubernetes namespace is already created in IBM Cloud

• Wishlist team members have access to the nyu-cluster

  Acceptance Criteria

  Given deployment files
  When wishlist team members execute `kubectl apply -f <dir>`
  Then the production version of wishlist and postgres services are deployed to IBM Cloud
