The helm-charts-with-caddy branch had the Caddy manifest file but was still
using nginx in the code. This change:
- Switch install_ingress_for_kind() to use ingress-caddy-kind-deploy.yaml
- Update wait_for_ingress_in_kind() to watch caddy-system namespace
- Use correct label selector for Caddy ingress controller pods
