   this pr can optimize user configuration of datasource. Typically configured 
datasource has a lot of duplicate properties
   old :
   ```yaml
   
spring.shardingsphere.datasource.ds.type=org.apache.commons.dbcp2.BasicDataSource
   spring.shardingsphere.datasource.ds.driver-class-name=org.h2.Driver
   
spring.shardingsphere.datasource.ds.url=jdbc:h2:mem:ds;DB_CLOSE_DELAY=-1;DATABASE_TO_UPPER=false;MODE=MYSQL
   spring.shardingsphere.datasource.ds.username=sa
   spring.shardingsphere.datasource.ds.password=
   
   
spring.shardingsphere.datasource.ds_0.type=org.apache.commons.dbcp2.BasicDataSource
   spring.shardingsphere.datasource.ds_0.driver-class-name=org.h2.Driver
   
spring.shardingsphere.datasource.ds_0.url=jdbc:h2:mem:ds_0;DB_CLOSE_DELAY=-1;DATABASE_TO_UPPER=false;MODE=MYSQL
   spring.shardingsphere.datasource.ds_0.username=sa
   spring.shardingsphere.datasource.ds_0.password=
   ```
   
   now : 
   ```yaml
   
spring.shardingsphere.datasource.common.type=org.apache.commons.dbcp2.BasicDataSource
   spring.shardingsphere.datasource.common.driver-class-name=org.h2.Driver
   spring.shardingsphere.datasource.common.username=sa
   spring.shardingsphere.datasource.common.password=
   
   
spring.shardingsphere.datasource.ds.url=jdbc:h2:mem:ds;DB_CLOSE_DELAY=-1;DATABASE_TO_UPPER=false;MODE=MYSQL
   
spring.shardingsphere.datasource.ds_0.url=jdbc:h2:mem:ds_0;DB_CLOSE_DELAY=-1;DATABASE_TO_U
   ```
   Of course, you can also customize to override common properties.
