[ENHANCEMENT] Highlight jobs which produced warnings

[MBartkowiakSTFC]

Is your feature request related to a problem? Please describe. At the moment, the users have to click on each job in the GUI to view its log. Since we have are gradually adding meaningful warnings to different jobs, it would be good to attract the user's attention to the jobs which produced warnings.

Describe the solution you'd like We could either create a new job status for "finished, but with warnings", to differentiate it from those that just finished, or highlight them in the table.

Describe alternatives you've considered We could also mark the logger tab for the user when a warning pops up, but this is probably not specific enough and the users will start ignoring it quickly.
