WIP: Resolve "Show `failure_reason` in Job page"

What does this MR do?

Show a failure reason on the Job page

Why was this MR needed?

When a job fails, we have no direct way to know which is the problem. The only option is to look at job details and read the output log, where we can possibly see some error message. In case the job failed for reasons that prevent an output log at all, we have no way to know about the error
