This adds a couple of metrics for tracking the timing and frequency of method calls: - rpc/requests gauge counts all requests - rpc/success gauge counts requests which return err == nil - rpc/failure gauge counts requests which return err != nil - rpc/duration/all timer tracks timing of all requests - rpc/duration/<method>/<success/failure> tracks per-method timing
