Custom metrics

import "github.com/asjard/asjard/core/metrics"

func main() {
	// Register a counter metric
	// If registration succeeds, counter returns a non-nil value; if registration fails it returns nil
	// Can be registered repeatedly
	// If pushgateway is configured, these labels cannot be included: app, env, service, service_version, instance
