Kotlin calling OkHttp 4.x:

```kotlin
val client = OkHttpClient.Builder()
    .dns(object : Dns {

          InetAddress.getAllByName(hostname).toList()
    })
    .build()
```

SAM conversion impacts these APIs:

// Enabled returns if AuthZPlugin is enabled.
func Enabled(kvs config.KVS) bool {

}

// LookupConfig lookup AuthZPlugin from config, override with any ENVs.
func LookupConfig(s config.Config, httpSettings xhttp.ConnSettings, closeRespFn func(io.ReadCloser)) (Args, error) {
