Review comment:
I'll make this to Map<OmKeyArgs, String> to consistent with the
renameKey() API.
In addition, the API was added to OzoneBucket and currently only supports
renaming keys under the same bucket.
`OzoneBucket bucket = volume.getBucket(bucketName);`
`Map<String, String> keyMap = new HashMap();`
`keyMap.put(keyName1, newKeyName1);`
`bucket.renameKeys(keyMap);`
