This task involves preparing a scenario within the `openshift-pipelines/performance` framework to simulate a burst of new PipelineRuns, which is crucial for testing the hypothesis that Tekton Results may fail to store PLRs during API latency spikes. The scenario will utilize existing functionality allowing for varying concurrency over time: initially, 1 concurrency for 10 minutes, followed by a burst of 300 concurrency for 1 minute, and then returning to 1 concurrency for 10 minutes. The goal is to confirm that this burst scenario can be successfully configured and executed by modifying the existing test suite, and to make any necessary code changes to the performance framework to enable this specific load profile.
