Improve autoscaler e2e logging (#4456)

* Improve autoscaler e2e logging - it looks like the AS returns scaling events 1-2 mins after they occur, which is too late for the test - add additional logging to print out event table data in case of alternative events being raised - fix logging if wait for events times out - add hint in later test that depends on AS scaling event * Ensure only the schedule rule results in scaling events
