### SUMMARY Currently the pivot operation doesn't work properly on the chart data endpoint due to column names being `Tuple[str, ...]`, causing `json.dumps` to fail. This adds the option to flatten the column names in a similar manner to how `viz.py` does it (drop metric name if only single metric present, join column names with comma etc). In addition, the index is returned to the DataFrame as a regular column to keep the pivot output uniform with other post processing operations. The `columns` argument is also made optional to avoid having to do an additional ternary in `buildQuery` when building time series viz plugins. ### TEST PLAN CI + new tests ### ADDITIONAL INFORMATION <!--- Check any relevant boxes with "x" --> <!--- HINT: Include "Fixes #nnn" if you are fixing an existing issue --> - [ ] Has associated issue: - [ ] Changes UI - [ ] Requires DB Migration. - [ ] Confirm DB Migration upgrade and downgrade tested. - [ ] Introduces new feature or API - [ ] Removes existing feature or API ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
