[Catskan]

What

By changing api-server by workload-api-server, ingress template is missing for workload_api_server while values.yaml have the capability to enable ingress for workload-api-server . So actually, workload-api-server is unable to create the related ingress.

How

Just add the ingress template to charts/workload-api-server/templates
