Research: Enhance CMS performance by freeing up urllib connection pool

[patphongs]

Summary

We may be able to enhance CMS performance by freeing up Django DB connections.

Things to try when locust testing

• Use non_atomic_requests inside the data views to decrease db transactions. Check to see if the number of CMS DB transactions have decreased. Locust test specifically view functions that utilize non_atomic_requests.
• See if we need to increase gunicorn workers if non_atomic_requests are freeing up transactions from api_caller dependent view requests.
