* Implement basic S3 notifications through queues Supports multiple queues and three basic queue types: 1. NilQueue -- messages don't get sent anywhere 2. LogQueue -- messages get logged 3. AmqpQueue -- messages are sent to an AMQP queue * api: Implement bucket notification. Supports two different queue types - AMQP - ElasticSearch. * Add support for redis
