[ML] Change the text on swimlane popup to refer to "Max Influencer Score"

[elasticmachine]

Original comment by @richcollier:

The popup in the swimlane shows:

but this isn't the max "anomaly score" - it is the max influencer score. The scoring is confusing enough without this label being inconsistent.

Original comment by @peteharverson:

@richcollier note that when viewing by job ID, the anomaly_score field from the bucket level results is displayed. And for the overall swimlane, the overall_score field from the overall_buckets endpoint is displayed. We originally decided on 'anomaly score' as the label used across swimlane to avoid possible confusion by presenting several 'score' terms in the view.

So the options here are sticking with the existing 'Max anomaly score' label for all three places, or switching to 'Max score' for all three, or using 'Max overall score', 'Max influencer score' and 'Max bucket score' (or should that be 'Max bucket anomaly score' or 'Max anomaly score'!).

Original comment by @richcollier:

@peteharverson - I vote for the last option:

• Max overall score
• Max influencer score
• Max anomaly score

In the appropriate place...People are still confused by seeing red for a square in the swimlane for an influencer, but when clicking on it, only see a blue anomaly for that influencer

They assume that they should see a red anomaly too

I totally agree with @richcollier. To reduce confusion of users, the label should describe more precisely what kind of score is shown. Otherwise the whole view makes a very inconsistent and thus unreliable impression.
