使用Kvass+Prometheus监控多个K8S集群集时不支持

[cvimer]

场景：

1. 统一的监控集群，infra
2. 多个业务集群，test/a/b
3. infra集群中的kvass+prometheus监控其他集群

结果：

1. 原配置文件

    - job_name: 'cluster-test/kube-state-metrics/0'
      kubernetes_sd_configs:
        - role: endpoints
          namespaces:
            names:
              - obser
          api_server: https://172.16.36.151:6443
          tls_config:
            ca_file: /etc/prometheus/tls/cluster-test-ca.crt
          bearer_token_file: /etc/prometheus/tls/cluster-test-token
      tls_config:
        ca_file: /etc/prometheus/tls/cluster-test-ca.crt
      bearer_token_file: /etc/prometheus/tls/cluster-test-token
      relabel_configs:
        ...

1. 生成配置文件

- job_name: cluster-test/kube-state-metrics/0
  honor_timestamps: true
  scrape_interval: 15s
  scrape_timeout: 10s
  metrics_path: /metrics
  scheme: http
  authorization:
    type: Bearer
    credentials_file: /etc/prometheus/tls/cluster-test-token
  proxy_url: http://127.0.0.1:8008
  follow_redirects: true
  relabel_configs:
  - separator: ;
    regex: __invalid_label_(.+)
    replacement: $1
    action: labelmap

kvass并没有将外部的k8s监控起来，没有生成静态配置
如果是只监控本集群内部，配置是正确生成了的，但是外部集群的静态target未生成,
如果我单独使用Prometheus是无问题的

忽略，配置问题，已测试通过
