Growth: revisit collecting usage metrics for user pilot

[genehynson]

We had to turn off feature flag newUsageAPI because it was causing performance issues in the UI. This flag was collecting usage data over the past 30 days and sending it to user pilot. Let's investigate a different method to collect this data that doesn't bog down the browser. Perhaps a direct integration between user-pilot and our backend APIs? Or a custom query that doesn't return a large result?

Where the flag is used in the UI:
