URL: https://github.com/apache/shardingsphere/issues/18695

   Hi community, 
   
   We recently refactor `readwrite-splitting` feature `API`, you can refer to 
#18587, #18629.
   
   So, we need to modify `RDL` about `READWRITE_SPLITTING RULE`. 
   
   Now CREATE or ALTER Dynamic `READWRITE_SPLITTING RULE` DistSQL are : 
   
   // Dynamic
   ```
   CREATE READWRITE_SPLITTING RULE ms_group_1 (
   AUTO_AWARE_RESOURCE=group_0
   );
   ```
   
   ```
   ALTER READWRITE_SPLITTING RULE ms_group_1 (
   AUTO_AWARE_RESOURCE=group_1
   );
   ```
   
   Hope to adjust to : 
   
   // Dynamic
   ```
   CREATE READWRITE_SPLITTING RULE ms_group_1 (
   AUTO_AWARE_RESOURCE=group_0,
   WRITE_DATA_SOURCE_QUERY_ENABLED='true'
   );
   ```
   
   ```
   ALTER READWRITE_SPLITTING RULE ms_group_1 (
   AUTO_AWARE_RESOURCE=group_1,
   WRITE_DATA_SOURCE_QUERY_ENABLED='false'
   );
   ```
   
   - [ ] Adjust `shardingsphere-readwrite-splitting-distsql-handler` 
RDLStatement.g4 file.
   - [ ] Modify `CreateReadwriteSplittingRuleStatementUpdater.class` and 
`AlterReadwriteSplittingRuleStatementUpdater.class`.
   - [ ] Modify document
   
   1. 
https://shardingsphere.apache.org/document/current/cn/user-manual/shardingsphere-proxy/distsql/syntax/rdl/rule-definition/readwrite-splitting/
   
   - [ ] Fix shardingsphere-integration-test module.
