To improve user experience in datasource page, add default port for each type database.

1. When create or edit datasource, there is a default vaule for port. If user changes type, the default value changes.
2. Use local variables in browser memory, to cache user previous input port for each type. For example :
	     time-a:  MySQL default  port is 3306 , user change 3306 to 4000.
         time-b:  User change type from MySQL to ClickHouse , the port change  from 4000 to 8123.
         time-c:  User change type from ClickHouse back to MySQL，the port change from 8123 to 4000，use previous input cache to fillback.

3. In edit datasource page, when the page first loads, use the query value fillback instead of default value.

When create an resource the name will add the suffix, But When rename the resource there is no suffix add to the name, So When update resource name without suffix just like "test.sh" => "test" , Then the bug reproduced.

To fix this bug i add the logic bellow:
When rename, if the name without suffix then add it ,else use the origin name
