feat: Ce 1222 load tests

[mikevespi]

Added load testing code and configuration to the repository.

Description

This PR introduces code to perform load tests on the application. More details, including instructions, can be found in performance_tests/README.md. K6 tooling was used to write the tests, which include back- and front-end protocol level tests as well as browser level tests for the front-end which simulates a user logging in and using the app. A sibling PR was created to add more test data prior to running the tests.

Platform Services are to be notified before running tests beyond the smoke test level load.

The new Sonarqube warnings are based on the use of var in the test scripts. While this is seen as bad practice, it was intentional in the test scripts as we're taking a bit of advantage of the scope mechanics that var has.
