When Metric threshold alert is triggered for "Warning" threshold, we need to adjust "Observed value" and "Threshold" to use warning threshold instead of alert threshold. In case, if it is not possible to use warning threshold, we should display "-" instead.
Add both/all thresholds ("error", "warning") in this view
Remove the "percent difference" parenthetical from this view (to remove confusion around which to show) - this parenthetical seems to be adding noise and, especially in this single alert view, doesn't add much information above the raw numbers being there (I understand how that would be nice in a setting where you are comparing across many alerts)
cc: @maciejforcone are you ok with this plan, especially here for Metric Threshold rule?
