[Command] [SQL] Add show database/table/partition id command (#5807)

Browse Source 
In BE, when a problem happened, in the log, we can find the database id, table id, partition id,
but no database name, table name, partition name.

In FE, there also no way to find database name/table name/partition name accourding to
database id/table id/partition id. Therefore, this patch add 3 new commands:

1. show database id;
mysql> show database 10002;
+----------------------+
| DbName               |
+----------------------+
| default_cluster:test |
+----------------------+

2. show table id;
mysql> show table 11100;
+----------------------+-----------+-------+
| DbName               | TableName | DbId  |
+----------------------+-----------+-------+
| default_cluster:test | table2    | 10002 |
+----------------------+-----------+-------+

3. show partition id;
mysql> show partition 11099;
+----------------------+-----------+---------------+-------+---------+
| DbName               | TableName | PartitionName | DbId  | TableId |
+----------------------+-----------+---------------+-------+---------+
| default_cluster:test | table2    | p201708       | 10002 | 11100   |
+----------------------+-----------+---------------+-------+---------+
