Description

Some improvements that could make the /log_level page more intuitive.

• The current log level configurations could be printed when the page is loaded.
  • The glog level disappears after page reload.
  • The 'Get Java Log Level' is inconvenient to use.
• The titles/naming could be more consistent, for example currently "Change Java log level" and "Change backend logging level", could be frontend&backend.
