Pod startup time phases are inaccurate in longer tests.

[wojtek-t]

gatherScheduleTimes:
https://github.com/kubernetes/perf-tests/blob/master/clusterloader2/pkg/measurement/common/slos/pod_startup_latency.go#L268
is currently listing events at the end of the test.

Given that events by default have 1h TTL, for measurements across longer periods it just returns incomplete results. Given that we don't 100% accuracy, we should switch to a mechanism that is similar to the one that slo-monitor is using (added in #1477 ).
