request help: request id 和 通过 response 取的 request id 不一样 ，是否有什么规则？

### Issue description
request id 和 通过 response 取的 request id 不一样， 请问有什么规则？ 除了通过ID的方式，是否还有其他方式可以根据response 获取到对应的 request？

插件代码如下
```
package plugins

import (
"net/http"

pkgHTTP "github.com/apache/apisix-go-plugin-runner/pkg/http"
"github.com/apache/apisix-go-plugin-runner/pkg/log"
"github.com/apache/apisix-go-plugin-runner/pkg/plugin"
)

func init() {
err := plugin.RegisterPlugin(&CheckId{})
if err != nil {
log.Fatalf("failed to register plugin check_id: %s", err)
}
}

// Say is a demo to show how to return data directly instead of proxying
// it to the upstream.
type CheckId struct {
// Embed the default plugin here,
// so that we don't need to reimplement all the methods.
plugin.DefaultPlugin
}

type CheckIdConf struct {
}

func (p *CheckId) Name() string {
return "check_id"
}

func (p *CheckId) ParseConf(in []byte) (interface{}, error) {
return CheckIdConf{}, nil
}

func (p *CheckId) RequestFilter(conf interface{}, w http.ResponseWriter, r pkgHTTP.Request) {
log.Infof("run request filter, r.ID() %d", r.ID())
}

func (p *CheckId) ResponseFilter(conf interface{}, w pkgHTTP.Response) {
log.Infof("run response filter, w.ID() %d", w.ID())
}

```

当发送请求时控制台输出

```

```
request filter 中获取的 request id 跟 responsor filter中获取的request id 不一致，分别是 4194308 和 4194309
