[Logs UI] Support error.stack_trace

[felixbarny]

The field error.stack_trace has recently been added to ECS: elastic/ecs#562

This issue is about supporting that field with the default log layout.

If error.stack_trace is available, it should be rendered after the message in a new line.

If it's possible, it would be great if the Logs app could also handle the case where error.stack_trace is an array, containing each line of the stack trace in a new array element. In that case, it should just join all lines like this event.get("error.stack_trace").join("\n"). For more background on that use case, see the ECS PR (elastic/ecs#562).

We're planning to GA ECS loggers in 7.11.
Any chance we could prioritize this issue for the near-term?

Thanks for the bump, I'll bring it up during the 7.12 planning.

Hi, any updates?

The PR @felixbarny has put together (#94906) looks like a big step into this direction. I hope to get around to reviewing and merging it soon ™️.
