兜底路由在1.11 istio 不生效

Bug description

slime v0.7.0支持ip:port格式域名透传功能，使用了istio 1.11还不支持的 string_match

导致下发至envoy后配置的缺失，导致所有格式的的域名都被透传了，懒加载无法生效。

           - domains:
              - '*'
              name: to_global_sidecar
              routes:
                - match:
                    prefix: /
                    headers:
                    - name: ':authority'
                      string_match:
                        safe_regex:
                          google_re2: {}
                          regex: '^(?:(?:25[0-5]|2[0-4][0-9]|[01]?[0-9][0-9]?)\.){3}(?:25[0-5]|2[0-4][0-9]|[01]?[0-9][0-9]?)(?::([1-9]|[1-9]\d{1,3}|[1-5]\d{4}|6[0-5][0-5][0-3][0-5]))?$'
                  route:
                    cluster: PassthroughCluster
                    timeout: 0s
                - match:
                    prefix: /
                  route:
                    cluster: outbound|{{ $gsPort }}||global-sidecar.{{ $clusterGsNamespace }}.svc.cluster.local
                    timeout: 0s

最终导致下发的配置只有

           - domains:
              - '*'
              name: to_global_sidecar
              routes:
                - match:
                    prefix: /
                    headers:
                    - name: ':authority'
                    cluster: PassthroughCluster
                    timeout: 0s
