helm安装时gzip也给个配置吧

[w7team]

    gzip:
      enable: true
      minContentLength: 1024
      contentType:
        - text/plain
        - text/html
        - application/json
        - text/css
        - application/javascript
        - application/xhtml+xml
        - image/svg+xml
      disableOnEtagHeader: true
      memoryLevel: 5
      windowBits: 12
      chunkSize: 4096
      compressionLevel: BEST_COMPRESSION
      compressionStrategy: DEFAULT_STRATEGY

像downstream一样，可以helm set配置
