logging: don't change the log level in the handler config I find it confusing that even though the log level for sqlalchemy.engine was INFO, because the log level of handler_console_sql was WARN, there were no INFO output from sqlalchemy.engine. Therefore remove the level setting for the handlers in the default settings. I think this makes it (a bit) more intuitive.
