[Feature] Support show data order by

[DinoZhang]

Currently, the show data does not support sorting. When the number of tables increases, it is inconvenient to manage. Need to support sorting

syntax:

SHOW DATA [FROM db_name[.table_name]] [ORDER BY ...];

like:

mysql>  show data order by ReplicaCount desc,Size asc;
+-----------+-------------+--------------+
| TableName | Size        | ReplicaCount |
+-----------+-------------+--------------+
| table_c   | 3.102 KB    | 40           |
| table_d   | .000        | 20           |
| table_b   | 324.000 B   | 20           |
| table_a   | 1.266 KB    | 10           |
| Total     | 4.684 KB    | 90           |
| Quota     | 1024.000 GB | 1073741824   |
| Left      | 1024.000 GB | 1073741734   |
