Default logger doesn't print log level.

Issue Description

I'm using middleware.Logger() and sometimes in the app log.Error() or log.Info(). The middleware.Logger() however never prints a log level for requests. Shouldn't this be like always "INFO"? This is annoying as it's harder to parse all logs in splunk. Is there any easy workaround?
