feat(load-balancer): Different health check options per service/port

[DarkZatarra]

We have the following code:

kind: Service
metadata:
  name: abcd-com
  namespace: abcd-prod
  annotations:
    load-balancer.hetzner.cloud/name: "farm-waf-razdon-com"
    load-balancer.hetzner.cloud/location: fsn1
    load-balancer.hetzner.cloud/protocol: "tcp"
    load-balancer.hetzner.cloud/uses-proxyprotocol: "true"
    load-balancer.hetzner.cloud/use-private-ip: "true"
    load-balancer.hetzner.cloud/disable-public-network: "false"
    load-balancer.hetzner.cloud/health-check-protocol: "http"
    load-balancer.hetzner.cloud/health-check-http-validate-certificate: "true"
    load-balancer.hetzner.cloud/health-check-http-domain: "abcd.com"
    load-balancer.hetzner.cloud/health-check-http-path: "/hcheck"
spec:
  selector:
    app: abcd-com
  ports:
    - port: 443
      targetPort: 443
      name: "https"
    - port: 80
      targetPort: 80
      name: "http"
  type: LoadBalancer

And we want to have the possibility to run a check on http without validate-certificate and a check on https with validate-certificate.
We tried the following:

kind: Service
metadata:
  name: abcd-com
  namespace: abcd-prod
  annotations:
    load-balancer.hetzner.cloud/name: "farm-waf-razdon-com"
    load-balancer.hetzner.cloud/location: fsn1
    load-balancer.hetzner.cloud/protocol: "tcp"
    load-balancer.hetzner.cloud/uses-proxyprotocol: "true"
    load-balancer.hetzner.cloud/use-private-ip: "true"
    load-balancer.hetzner.cloud/disable-public-network: "false"
    load-balancer.hetzner.cloud/health-check-protocol-443: "https"
    load-balancer.hetzner.cloud/health-check-http-validate-certificate-443: "true"
    load-balancer.hetzner.cloud/health-check-http-domain-443: "abcd.com"
    load-balancer.hetzner.cloud/health-check-http-path-443: "/hcheck"
    load-balancer.hetzner.cloud/health-check-protocol-80: "http"
    load-balancer.hetzner.cloud/health-check-http-validate-certificate-80: "false"
    load-balancer.hetzner.cloud/health-check-http-domain-80: "abcd.com"
    load-balancer.hetzner.cloud/health-check-http-path-80: "/hcheck"
spec:
  selector:
    app: abcd-com
  ports:
    - port: 443
      targetPort: 443
      name: "https"
    - port: 80
      targetPort: 80
      name: "http"
  type: LoadBalancer

But it's seems it's not supported.

There real question is how can we control the healthcheck options per port?

Thanks!

P.S. in first code quote the health-check-protocol set to https gives error - that's why we've set it to http

#324 seems somewhat related to this: making it possible to more finely tune the healthcheck configuration.
