ElvinWei 5dfdacd278 [enhancement](histogram) add histogram syntax and perstist histogram statistics (#15490)
Histogram statistics are more expensive to collect and we collect and persist them separately.

This PR does the following work:
1. Add histogram syntax and add keyword `TABLE`
2. Add the task of collecting histogram statistics
3. Persistent histogram statistics
4. Replace fastjson with gson
5. Add unit tests...

Relevant syntax examples:
> Refer to some databases such as mysql and add the keyword `TABLE`.

```SQL
-- collect column statistics
ANALYZE TABLE statistics_test;

-- collect histogram statistics
ANALYZE TABLE statistics_test UPDATE HISTOGRAM ON col1,col2;
```
