Support new grammar: `table_name$partitions`
User can query partition info by using:
```
select * from table_name$partitions
```
`table_name$partitions` is a special meta table corresponding to the
table.
Its schema is the partition columns of the table, and column type is
always "String".
And the value is the partition column's value
You can use `DESC table_name$partitions` to get schema:
```
mysql> desc partition_values_all_types$partitions;
+-------+----------------+------+------+---------+-------+
| Field | Type | Null | Key | Default | Extra |
+-------+----------------+------+------+---------+-------+
| p1 | boolean | Yes | true | NULL | NONE |
| p2 | tinyint | Yes | true | NULL | NONE |
| p3 | smallint | Yes | true | NULL | NONE |
| p4 | int | Yes | true | NULL | NONE |
| p5 | bigint | Yes | true | NULL | NONE |
| p6 | date | Yes | true | NULL | NONE |
| p7 | datetime(6) | Yes | true | NULL | NONE |
| p8 | varchar(65533) | Yes | true | NULL | NONE |
| p9 | decimal(9,2) | Yes | true | NULL | NONE |
| p10 | decimal(18,10) | Yes | true | NULL | NONE |
| p11 | decimal(38,9) | Yes | true | NULL | NONE |
+-------+----------------+------+------+---------+-------+
```
Where `px` are partition columns of table `partition_values_all_types`;
```
mysql> select * from partition_values_all_types$partitions order by p1,p2,p3;
+------+------+--------+-------------+----------------------+------------+----------------------------+--------+-------------+----------------------+------------------------------------------+

```
Currently, this grammar can only be used for partition table's in Hive
Catalog.
Table in other catalogs or non partition table can not use this grammar.
Internally, it is implemented as a table valued function:
`partition_values`
```
mysql> select * from partition_values("catalog" = "hive", "database" = "multi_catalog", "table" = "partition_values_all_types");
