Increase compatibility with mysql
  1. Added two system tables files and partitions

  4. Compatible with mysqldump tool, now you can use mysql dump to dump data and table structure from doris

now use mysqldump may print error message like 
```
$ mysqldump -h127.0.0.1 -P9130 -uroot test_query_qa > a
mysqldump: Error: 'errCode = 2, detailMessage = select list expression not produced by aggregation output (missing from GROUP BY clause?): `EXTRA`' when trying to dump tablespaces
