ignore addresses for kubernetes registry

[butonic]

We no longer pass an address to the go micro kubernetes registry implementation. This causes the implementation to autodetect the namespace and not hardcode it to default.

related #8589

related code in the implementation:

	// get first host
	var host string
	if len(k.options.Addrs) > 0 && len(k.options.Addrs[0]) > 0 {
		host = k.options.Addrs[0]
	}

	if k.options.Timeout == 0 {
		k.options.Timeout = time.Second * 1
	}

	// if no hosts setup, assume InCluster
	var c client.Kubernetes
	if len(host) == 0 {
		c = client.NewClientInCluster()          // <---- this picks up the namespace from the pod
	} else {
		c = client.NewClientByHost(host)         // <---- this hardcodes the namespace to "default"
	}

when the namespace is default, all services will be registered in the default namespace. but then nothing would work and pods from multiple ocis instances in the same kubernetes cluster but in different namespaces would 'see' each other. 🤔
