Use Regex Matches in Resource Template

[Edward13ruf]

It would be incredibly powerful for the match groups from the regex used to match the namespace name to be available to the resource template.

namespace: my-ns-1
regex: my-ns-(?<id>\d+)
resources:

 apiVersion: rbac.authorization.k8s.io/v1
    kind: RoleBinding
    metadata:
      name: dev-rolebinding
    subjects:
    - kind: Group
      name: my-group:${id}
    roleRef:
      kind: Role
      name: dev-role
      apiGroup: rbac.authorization.k8s.io
