Review comment:
hmm, I don't really like that we're always sending at least 2 requests,
as long as at least one counter and gauge exist.
Ultimately, all we need to do is slice the currently created `DSeries`,
which we could do using `ArrayList#subList`.
```
int fromIndex = 0;
ArrayList<DMetric> series = request.getSeries();
while (fromIndex < series.size()) {
int toIndex = Math.Min(currentCount + maxMetricsPerRequestValue,
series.size());
client.send(series.subList(fromIndex, toIndex));
fromIndex = toIndex;
}
```
WDYT? We could even wrap this logic into a stateful `Consumer` that resets
the `DSeries` on each `client.send`, so we don't have to assemble the full list.
