Patrick Ohly eaa95b9178 test/integration/logs: benchmark using logsapi
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".
