In #708, the webhook server was made specific (and K3d/K3s is configured). However, when tested in the "thorough tests" after the merge, the e2e tests failed on the Minikube cluster — because it has a different magic hostname:
host.minikube.internal
instead ofhost.k3d.internal
.To make it work automatically in CI/CD, and in most other cases, this PR adds a feature to automatically detect the cluster type (among the limited list of options: Minikube, K3d/K3s only). Users can also configure auto-tunnel, which will fall back to ngrok if the cluster type cannot be detected; the auto-server will run a simple local server in that case.
