K8SPXC-876 use PublishNotReadyAddresses instead of annotation

https://jira.percona.com/browse/K8SPXC-876
"service.alpha.kubernetes.io/tolerate-unready-endpoints" annotation has been
deprecated since Kuberneets 1.8 and the spec.publishNotReadyAddresses
parameter replacing it has been correctly implemented in Kubernetes 1.11
(see kubernetes/kubernetes#63742)
