Title: Generate a request_id in development.

@alexakarpov pointed out that Rack::Lint doesn't play nicely with this in development, since we set X-Request-Id to a nil value. This adds a configuration option to enable or disable generation of a request_id using SecureRandom. By default, it's enabled in Rails when the environment is development.
