- Add Kubernetes secrets engine at kubernetes/au/syd1 path
- Create four RBAC roles with external YAML configuration:
* media-apps-operator: namespaced role for media-apps with selective permissions
* cluster-operator: cluster-wide read-only access to specific API groups
* cluster-admin: cluster-wide full access to specific API groups
* cluster-root: cluster-wide superuser access to all resources
- Add Vault policies for credential generation for each role
- Add admin policies for kubernetes auth backend configuration and role management
- Refactor kubernetes auth backend to use shared locals for CA certificate
- Update terraform-vault approle with required kubernetes policies
