Review comment:
I do like the sublist approach although `DatadogHttpClient` serializes a
`DSeries` not a `List`.
maybe something like:
```
List<DMetric> metrics = new ArrayList();
addGaugesAndUnregisterOnException(metrics);
metrics.addAll(counters.values());
metrics.addAll(meters.values());
int fromIndex = 0;
while (fromIndex < metrics.size()) {
int toIndex = Math.Min(fromIndex + maxMetricsPerRequestValue,
metrics.size());
client.send(new DSeries(metrics.subList(fromIndex, toIndex)));
fromIndex = toIndex;
}
```
