Issue Number: close #xxx
## Problem Summary:
In some cases, we would like to check the status of `rowsets` and
`segments`. So I add the `segments` table into information_schema database .
The table schema of `segments` is:
```
MySQL [(none)]> desc information_schema.segments;
+-------------------+------------+------+-------+---------+-------+
| Field | Type | Null | Key | Default | Extra |
+-------------------+------------+------+-------+---------+-------+
| ROWSET_ID | VARCHAR(*) | Yes | false | NULL | |
| TABLET_ID | BIGINT | Yes | false | NULL | |
| ROWSET_NUM_ROWS | BIGINT | Yes | false | NULL | |
| TXN_ID | BIGINT | Yes | false | NULL | |
| PARTITION_ID | BIGINT | Yes | false | NULL | |
| NUM_SEGMENTS | BIGINT | Yes | false | NULL | |
| START_VERSION | BIGINT | Yes | false | NULL | |
| END_VERSION | BIGINT | Yes | false | NULL | |
| INDEX_DISK_SIZE | BIGINT | Yes | false | NULL | |
| DATA_DISK_SIZE | BIGINT | Yes | false | NULL | |
| SEGMENT_VERSION | BIGINT | Yes | false | NULL | |
| SEGMENTS_NUM_ROWS | BIGINT | Yes | false | NULL | |
+-------------------+------------+------+-------+---------+-------+
```
and then we can search `rowsets` and `segments` info from `segments` table,
like this:
```
MySQL [(none)]> select * from information_schema.segments limit 10;
+--------------------------------------------------+-----------+-----------------+--------+--------------+--------------+---------------+-------------+-----------------+----------------+-----------------+-------------------+
| ROWSET_ID | TABLET_ID |
ROWSET_NUM_ROWS | TXN_ID | PARTITION_ID | NUM_SEGMENTS | START_VERSION |
END_VERSION | INDEX_DISK_SIZE | DATA_DISK_SIZE | SEGMENT_VERSION |
SEGMENTS_NUM_ROWS |
+--------------------------------------------------+-----------+-----------------+--------+--------------+--------------+---------------+-------------+-----------------+----------------+-----------------+-------------------+
