Rack Timeout support

[matthewford]

Hello,

We're using https://github.com/heroku/rack-timeout

They seem to have rollbar support, where each timeout is grouped by URL, any ideas on how we could do something similar with sentry/raven?

Would love to support it. We'd add something to the integrations folder.

Coming soon to a release near you, or you can just drop #538 into your config/initializers to get it now.
