[statsd] timing sums

[rijnhard]

Feature Request

I may have had a moment of idiocy, but I did dig and look repeatedly.
According to the etsy statsd timing spec timers are supposed to have sum aggregates aswell, but telegraf does not seem create these when writing to influx.

Proposal:

Current behavior:

Telegraf creates mean, upper, lower, percentiles, stddev and count but not sum for timings.

Desired behavior:

Create <field>_sum field to match etsy statsd spec

Use case:

It simplifies queries, because now in order to get the sum I have to <field>_mean * <field>_count which isn't the end of the world, but not ideal as it requires subqueries pretty quickly when trying to doaggregations.
