Set scheduler event recorder in tests.

We accidentally removed the Recorder object from integration test
scheduler in kubernetes#71875. This
caused segfaults when running scheduler benchmarks.

    make test-integration WHAT="./test/integration/scheduler_perf" KUBE_TEST_ARGS="-run xx -bench ."

This change adds the recorder back.
