🐛 Bug Report

private void captureHttpStatusCount(HttpEntityEnclosingRequestBase httpRequestMethod, HttpResponse response) {
        String urlTag = "url=" + httpRequestMethod.getURI().getPath();
        String statusCode = statusCode(response);
        String httpCodeTag = statusCode.equals("null") ? "status_code=" : "status_code=" + statusCode;
        getInstrumentation().captureCount(SINK_HTTP_RESPONSE_CODE_TOTAL, 1, httpCodeTag, urlTag);
    }

URL can be unbounded which can results into large number of series.

Expected Behavior

URL tag should not be sent.

Steps to Reproduce

Steps to reproduce the behavior.

1. Run firehose
2. Have cortex series limit.
3. cortex will throw 400 when trying to push metrics after the series limit is reached.

Environment

Kubernetes
