http_requests_total is only available as a default metric

[jpslopes]

Hello, I noticed that the default metrics contain the metric http_requests_total. As this metric is only defined inside the method default, it was necessary to create it as a custom metric:

def http_requests_total(metric_namespace='', metric_subsystem='') -> Callable[[Info], None]:
    total = Counter(
        name="http_requests_total",
        documentation="Total number of requests by method, status and handler.",
        labelnames=(
            "method",
            "status",
            "handler",
        ),
        namespace=metric_namespace,
        subsystem=metric_subsystem,
    )

    def instrumentation(info: Info) -> None:
        total.labels(info.method, info.modified_status, info.modified_handler).inc()

    return instrumentation

It would be great to have this metric available as a method like latency and response_size.

Thanks!

Hey @jpslopes, yes I think this is a good improvement. Will integrate it this weekend. Thanks for raising it
