### What problem does this PR solve?
Introduce load job statistic system table:
```
mysql> show create table information_schema.load_jobs\G
*************************** 1. row ***************************
Table: load_jobs
Create Table: CREATE TABLE `load_jobs` (
`JOB_ID` text NULL,
`LABEL` text NULL,
`STATE` text NULL,
`PROGRESS` text NULL,
`TYPE` text NULL,
`ETL_INFO` text NULL,
`TASK_INFO` text NULL,
`ERROR_MSG` text NULL,
`CREATE_TIME` text NULL,
`ETL_START_TIME` text NULL,
`ETL_FINISH_TIME` text NULL,
`LOAD_START_TIME` text NULL,
`LOAD_FINISH_TIME` text NULL,

) ENGINE=SCHEMA;

```
User can use the `select * from information_schema.load_jobs` instead of
the `show load`. The advantage is that SQL can be very flexible in
locating jobs.
Example:
```
mysql> SELECT * FROM information_schema.load_jobs WHERE LABEL = 'test_load_job_label_b5347e94f2614e2c92705d6a6824a380'\G
