Collect some of scheduling metrics and scheduling throughput
In addition to getting overall performance measurements from golang benchmark, collect metrics that provides information about insides of the scheduler itself. This is a first step towards improving what we collect about the scheduler. Metrics in question: - scheduler_scheduling_algorithm_predicate_evaluation_seconds - scheduler_scheduling_algorithm_priority_evaluation_seconds - scheduler_binding_duration_seconds - scheduler_e2e_scheduling_duration_seconds Scheduling throughput is computed on the fly inside perfScheduling.
