Add classification of SQL_Type: this PR is just for DDL
Now we use the simple name to judge this operation belong to which
calssification of SQL_Type.
The SQL_Type will store in the spark's conf.
The configuration item's name is ${sql.type}.
Notice:
1. The classification of SQL_Type is based on Spark_v_3.1.2.
2. If the sql grammars have added in the future, the matching rule should
changed. We can add a configuration item that allow user to add the sql grammar
that the code is not defined.
### _Why are the changes needed?_
By these SQL_Type, we can do something below:
1. Reduce some log print:
For Auxiliary Statements(the sql type is others), we don't need to
print operation log.
2. Optimizing some configuration item.
For example, in final stage, the conf is different between DML and DQL.
Through this configuration item, we can use different conf for them.
### _How was this patch tested?_
- [ ] Add some test cases that check the changes thoroughly including
negative and positive cases if possible
- [ ] Add screenshots for manual tests if appropriate
- [ ] [Run
