fix(cluster_healthcheck): lookup all addresses
fix(cluster_healthcheck): lookup all addresses

`find_node_by_ip` wasn't looking in all the addresses available
since in k8s we might have multiple private network, it was
missing one of them (the cluster ip), and failing in the
health check casue of that

```
host ip: 10.0.1.35 (public_ip)
service ip: 10.0.1.8 (private_ip)
cluster ip: 172.20.132.155

Node sct-cluster-us-east1-b-us-east1-2 [10.0.1.35 | 10.0.1.8]
Get gossip info. Failed to find a node with status NORMAL in the cluster by IP: 172.20.132.155
