Review comment:
If `useFileMetaCacheList` config is used, without change the V2 API, it
seems that it can only be hard coded as
```
val metaCacheEnabled = useFileMetaCacheList.toLowerCase(Locale.ROOT)
.split(",").map(_.trim).contains("ORC")
```
the `formatName("ORC")` is defined `OrcTable`, we can't get it through the
API here at present.
