zhangdong 7a9fe5d275 [enhance](mtmv)MTMV supports Hive multi-level partitioning (#31060)
Issue Number: close #xxx

For example, the hive table is partitioned by `date` and `region`, with the following 6 partitions
```
20200101
        beijing
        shanghai
20200102
        beijing
        shanghai
20200103
        beijing
        shanghai
```

If the MTMV is partitioned by `date`, then the MTMV will have three partitions: 20200101, 202000102, 20200103

If the MTMV is partitioned by `region`, then the MTMV will have two partitions: beijing, shanghai
