### Purpose The current implementaion of the oss migration only support the same bucket. So you can't do a migration of a hive table from the bucket `a` to a paimon table at the bucket `b`. The limitation is due to the `AliyunOssFileSystem`'s `rename` implementation. It hard codes the source and target bucket to the same one. But the offical [document](https://www.alibabacloud.com/help/zh/oss/developer-reference/java-copy-objects?spm=a2c63.p38356.help-menu-31815.d_1_1_1_1_2_7.7d604065BNDXcM) of the aliyun oss doesn't have this limitation. So this pr is to overload the `rename` function to support the cross bucket data movement. ### Tests `OSSFileIOTest`'s mock test cases passed. And I test this by the real aliyun AK. -- This is an automated message from the Apache Git Service.
