    **Modify the partition will lose createTime.**
    Reading the hive partitions ignores createTime when converting the CatalogTablePartition, it will also be lost when modifying partitions.
    Calling this method SessionCatalog#alterPartitions will be lost createTime.
    So can you reopen this pr? @debugger87 
    
    ```sql
    CREATE  TABLE `tmp_test_partition`(
      `c1` string
    )
    PARTITIONED BY (
      `d` string
    );
    ALTER TABLE `tmp_test_partition_1` ADD PARTITION (d='1');
    ALTER TABLE `tmp_test_partition_1` PARTITION (d='1') SET LOCATION 'xxx';
    ```
