Enhancement request: InfluxDBListenerClient: Return response codes in all scenarios, not just errors

Hi

Currently the InfluxDBBackendListenerClient does not report the request response codes, except in the context of errors:

private void addErrorMetric(String transaction, ErrorMetric err, long count) {
if (count <= 0) {
return;
}
StringBuilder tag = new StringBuilder(70);
tag.append(TAG_APPLICATION).append(applicationName);
tag.append(TAG_TRANSACTION).append(transaction);
tag.append(TAG_RESPONSE_CODE).append(AbstractInfluxdbMetricsSender.tagToStringValue(err.getResponseCode()));
tag.append(TAG_RESPONSE_MESSAGE).append(AbstractInfluxdbMetricsSender.tagToStringValue(err.getResponseMessage()));
tag.append(userTag);

StringBuilder field = new StringBuilder(30);
field.append(METRIC_COUNT).append(count);
influxdbMetricsManager.addMetric(measurement, tag.toString(), field.toString());
}

Could this behaviour be changed so that the response codes are reported in all instances?
