The benchmarks and unit tests were written so that they used custom APIs for each log format. This made them less realistic because there were subtle differences between the benchmark and a real Kubernetes component. Now all logging configuration is done with the official k8s.io/component-base/logs/api/v1. To make the different test cases more comparable, "messages/s" is now reported instead of the generic "ns/op".
