vendor: Add dependency on google/uuid for safe UUID generation

etcd currently generates a few UUID style identifiers using approaches like `fmt.Sprintf("client-%s", strconv.FormatInt(time.Now().UnixNano(), 36))`.
But these can collide on machine architectures with larger timestamp steps (see https://github.com/etcd-io/etcd/issues/10035).
