fix(helm): Don't wait for service to be ready when external IP are set

Resolves #7513
As the externalIPs are not managed by k8s (according to the doc: https://kubernetes.io/docs/reference/generated/kubernetes-api/v1.17/#servicespec-v1-core) helm should not wait for services  which set al least one externalIPs.
