AS-382, AS-404: Getting load balancers in structured form

Do you think we should have any retries for these HTTP requests?

If so, maybe we could just encode that directly into the "request" function, so the caller has to set up the necessary retry logic? That'd work if the retry logic will be the same between all the different HTTP requests made by this function and keep the tests for this simple.
