Problem/Motivation
Same thing as #3463288: Consolidate test methods in StandardPerformanceTest.
The additional advantage if this works for the OpenTelemetry* tests is the performance test runner (a single dedicated gitlab runner) which can only run one set of tests at a time, and only at single concurrency to try to get consistent numbers, currently takes 13 minutes to complete all the tests it runs, and if we can cut that by a quarter, we should be able to generate consistent graphs for both the 11.x and 10.4.x branches.
See https://gander.tag1.io/ which currently only shows stats for 11.x due to this limitation.
