How Has This Been Tested?

Please describe the tests that you ran to verify your changes. Provide instructions so we can reproduce. Please also list any relevant details for your test configuration

• A new function named TestRateLimit has been written which sends 10 requests in one second to the api. Since the backend has it's middleware to limit to only a max of 5 api requests per second, only 5 should be allowed through whilst the other 5 are blocked.
• Ensuring that other ip addresses are not blocked from sending requests when one ip addresses is rate limited
