Merge branch 'cs-warn-on-failure' into 'master'

Warn on failure

## What does this MR do?

Adds styling and HTML for a `success_with_warnings` status in the MR widget. Unfinished as it needs some plumbing in the relevant CI controllers and models.

## Are there points in the code the reviewer needs to double check?

Not at the moment, though I think I'll probably need help getting this to work in the backend.

## What are the relevant issue numbers?

#17669 

## Screenshots (if relevant)
