Disable metrics and health checks ports in config daemon

We don't use metrics and health checks endpoints in the config daemon,
and they use common 8080/8081 ports by default, which might be taken
on a busy node. Since we have to use host network inside the pod,
this might result in a crash loop while waiting for the port to free up

The solution is to disable metrics and health checks until we need them
