Implemented functionality that handles reconnecting to the amqp server and reinitializing the amqp channel in case of errors and timeouts. This is handled by a goroutine created in the client constructor (it also handles the initial connect/init). Reconnects and reinits will use a fibonacci backoff strategy, and the attempt amount and max waiting interval can be adjusted by the 'reconnects' and 'max_reconnect_interval' config options. Messages that fail processing are now dropped instead of being requeued, preventing infinite processing loops. However, this means that the messages are lost. Handling failed messages will need to be addressed separately. 'concurrent_requests' will now set the prefetch count. Setting the prefetch count using the Qos function was able to replace our old approach that was using channels. Default value is 1024 which, according to the rabbitmq docs, 'runs into the law of diminishing returns'. The recommended value is between 100-300.
