For the node certificate resource, the IP address for localhost is set via the field
spec.dnsNames. This seems to work in the TLS clients used within Kubernetes.But it is not correct according to the standard. There are two separate extensions to be used for this. Cert-manager handles this by differentiating between
spec.dnsNamesandspec.ipAddresses.This change simply moves the IP address "127.0.0.1" into the appropriate field.
It should not change any behaviour, only avoid potential problems with more restrictive TLS clients.
