[SPIKE] Horizontally Scale Discovery API and Retest Performance

[christinepoydence]

What

Acceptance Criteria

• Horizontally scale the Discovery API in the dev environment.
• Re-run the same performance metrics to determine how much improvement this brings. (try various values to see how this scales.)
• If this results in significant performance improvement, write a card to make these changes in the helm chart.

Why

Improve performance time of REST API.

Verified that horizontally scaling the discovery-api deployment increased performance in the dev environment. (Went from 1 replica to 4, and saw significant performance increases.) However, we also are blocked by #1258. That error is preventing us from moving forward on this issue because a subset of our requests fail each time we run the performance test suite.

Next steps: We will create a card to increase the number of replicas for discovery-api and mark it as blocked by #1258.
