Sentry Metrics Backend Documentation

The sentry internal metrics backend is confusing me. I see DatadogMetricsBackend and also I see DogStatsdMetricsBackend.

I see that DatadogMetricsBackend uses Datadog’s ThreadStats so it is pretty handy to avoid running the datadog agent, but DogStatsdMetricsBackend is not documented, and also the only difference I see with the Statsd backend is that DogStatsdMetricsBackend supports some additional tags.

Hey @ParthKolekar!
I submitted this PR for review that adds docs on using the DogStatsD backend.

And the difference you’ve noted between the Statsd and DogStatsD backend about adding tags is exactly that - there’s a lot of power in adding tagging to any Datadog metrics.

Hope this helps!
