* go_metrics: adds new runtime metrics go_sched_latency_seconds - Distribution of the time goroutines have spent in the scheduler in a runnable state before actually running go_mutex_wait_total_seconds - Approximate cumulative time goroutines have spent blocked on a sync.Mutex or sync.RWMutex https://github.com/VictoriaMetrics/metrics/issues/54 * fixes data race * add tests * wip * wip --------- Co-authored-by: Aliaksandr Valialkin <valyala@victoriametrics.com>
