Notifications and Events

Several people have asked for better/deeper integration with instrumentation like ActiveSupport's notifications. Things which are log warnings today could be emitted as notifications, which are more flexible in where they go and how they can be monitored. For instance, the slow RTT warning or slow job iteration (i.e. an iteration which takes longer than Sidekiq's timeout setting).

Provide an adapter layer for AS::Notifications. Are there any other notification APIs of any significance in Ruby?
