Support create,insert/delete/update/select,show create table statement for list partition table.

Here is an example:

test> create table t (id int) partition by list  (id) (
   ->     partition p0 values in (1,2),
   ->     partition p1 values in (3,4),
   ->     partition p3 values in (5,null)
   ->     );
Query OK, 0 rows affected
Time: 0.006s
test> insert into t values (1),(3),(5),(null);
Query OK, 4 rows affected
Time: 0.004s
test> insert into t values (6);
(1526, 'Table has no partition for value 6')
test> select * from t partition (p0);
+----+
| id |
+----+
| 1  |
+----+
1 row in set
Time: 0.011s
test> delete from t partition (p0);
Query OK, 1 row affected
Time: 0.001s
test> select * from t;
+--------+
| id     |

| 3      |
| 5      |

   ->     partition p0 values in ((1,'a'),(2,'b')),
   ->         partition p1 values in ((3,'c'),(4,'d')),
   ->             partition p3 values in ((5,'e'),(null,null))
