Description of changes:
There is a defect where when saving multiple metrics, if one metric has a lot of values it will cause the the data to be split up into multiple line lines... however other metrics are then duplicates on each log line instead of only the first one.
For instance:
MetricA: 1
MetricB: 1,1,1,1,1 (1000 of them)
This will end up splitting things up into many lines, but each line will have MetricA, so the end result is that MetricA is saved multiple times, which is not intended.
This CR tracks what metrics had their values completely written to avoid the duplicates, and also adds a test that failed without the fix but now passes.
