Title: New "count" aggregator.

What do you think of integrating a `count()` aggregator?

I don't have relevant use case as a global aggregator, but I think it makes senses when downsampling, sometimes. For example, if you're plotting query latencies, you might want to consider min/max/avg/dev over a time period, but you might also want to check the number of requests you've processed.
