[Observability RAC] Severity column

[mgiota]

📝 Summary

As part of this #107029 the severity of the alerts is left empty if it's unknown. We should display a dash instead. In case it is a warning we should display warning.

✔️ Acceptance criteria

• diplay warning if it is a warning
• when the severity is not specified in the document, display a dash instead of it being empty
• for critical color badges we should use danger
• for warning color badges we should use warning

Note:

• let's look into whether severity can be indexed for more rule types

@katrin-freihofner Did I specify correctly the color names/classes?

UPDATE

• As mentioned in a comment below by @jasonrhodes we will remove this column for now.
• There were discussions around using simpler alert severity level mapping [RAC] [Observability] Use simpler alert severity level mapping #109068

@mgiota yes, it's a EuiBadge in color danger or warning as described - I will update the description.

We should show the empty cell if the value is not indexed, but we should consider making more of our rule types specify a severity explicitly so that we have less alerts with this "unknown" value.

Update: we may want to just remove this column for now if we don't have time to make sure the rule types are indexing the severity value. Ping @katrin-freihofner / @mdefazio just a heads up.
