Kind 0.31.0 brings a newer version of containerd which no longer supports configuring registry mirroes. Instead, we need to configure a `hosts.toml` file on all node containers per registry. This change configures the node to "resolve" `localregistry-docker-registry.default.svc.cluster.local:30050` to `localhost:30050` where `30050` is the twuni docker registry node port.
