cmd/containerboot,kube/kubetypes,cmd/k8s-operator: detect if Ingress is created in a tailnet that has no HTTPS This attempts to make Kubernetes Operator L7 Ingress setup failures more explicit: - the Ingress resource now only advertises HTTPS endpoint via status.ingress.loadBalancer.hostname when/if the proxy has succesfully loaded serve config - the proxy attempts to catch cases where HTTPS is disabled for the tailnet and logs a warning Updates tailscale/tailscale#12079 Updates tailscale/tailscale#10407 Signed-off-by: Irbe Krumina <irbe@tailscale.com>
