Add a "latency" stat in the dashboard

[jlecour]

I've added the latency metric in the /dashboard/stats response.

It is useful to collect metrics (for Munin or else) without using Ruby and Sidekiq's DSL at all.

That's the latency for the default queue. Maybe the metric should be called default_latency?

It would be useful to document /dashboard/stats on the Monitoring page.

I didn't realize that it was for the default queue but it makes total sense.

I guess we could have many possibilities :

• only the default queue
• each queue separately
• an average of all queues
• …

Do you know if Sidekiq users usually have many queues or just a few? I have 3-5.

[mperham]

We only have two: default and low. I think default is the only one we
should support.

The more I think about this the more I'd like to be able to customize this stat view, or add a custom one with my own use of Sidekiq's internal API.

If you merge this PR, I'll update the Monitoring page on the wiki.

Thanks!
