here the JVM level's LogLevel is set to be DEBUG.

source.getConnection()
-->DriverManager.getConnection(getUrl(), user, password)
->getUrl()
sb.append("&loglevel=").append(logLevel);

here the Connection's LogLevel is set to be the initial value 0(*) via URL,
although nobody set DataSource's LogLevel by calling BaseDataSource.setLogLevel().

I think it's better append "loglevel" to URL only when
BaseDataSource.setLogLevel() was called.
so a Connection created by DataSource.getConnection() can inherit JVM level's LogLevel setting
just like which one created by DriverManager.getConnection().

*)0 is the initial value and not a valid LogLevel,
valid values are INFO (1) and DEBUG (2).
