OCPBUGS-77026: DNS optimization, add trailing dots

[jotak]

Update getProxyServiceURL and getServiceURL to generate URLs with trailing dots, such as
"my-service.my-namespace.svc.cluster.local.:3000", which makes it unambiguous to the DNS resolver, speeding up DNS resolution by avoiding unnecessary queries.
