config key
URL: https://github.com/apache/incubator-shardingsphere/issues/3441
 
 
   ## Bug Report
   
   ### Which project did you use? Sharding-JDBC or Sharding-Proxy?
   I'm using sharding-jdbc v4.0.0-RC2:
   
   ```xml
           <dependency>
               <groupId>org.apache.shardingsphere</groupId>
               <artifactId>sharding-jdbc-spring-boot-starter</artifactId>
               <version>4.0.0-RC2</version>
           </dependency>
   ```
   ### Actual behavior
   #### the doc uses `username` for ds config

   #### but it raises an error that username is empty:

   #### problem is fixed when we chage the `username` to `name`

   ### Expected behavior
   the config key in `sharding-jdbc-spring-boot-starter` should be `username` 
or the config key in doc should be `user`
   
   ### Reason analyze (If you can)
   typo
